security: remove dead root files, harden CI permissions, add CodeQL workflow

CodeQL / security scanning fixes (v2.4.2):

- Delete stale root-level duplicate .py and .json files left over from
  before the v2.4.0 HACS restructure. They triggered duplicate CodeQL
  alerts on code that doesn't actually run, and could mislead HACS.
  Resolves CodeQL alert #2 (py/weak-sensitive-data-hashing on api.py root).

- Add permissions: contents: read to validate.yml (principle of least
  privilege). Resolves CodeQL alert #1 (actions/missing-workflow-permissions).

- Add explicit CodeQL workflow (.github/workflows/codeql.yml) with:
  - permissions: contents: read + security-events: write (minimum needed)
  - Scoped to custom_components/solar_of_things/ only
  - Weekly scheduled scan

- Add .github/codeql-config.yml:
  - Paths scoped to custom_components/solar_of_things/
  - Documented exclusion for py/weak-sensitive-data-hashing with rationale:
    the Siseli API mandates MD5(password) as a protocol requirement; the
    server returns error code 7 for plaintext. Not password storage.
    Transmitted over HTTPS only. Cannot be changed unilaterally.

- Add # noqa: S324 to api.py line ~315 with explanatory comment.
  Resolves CodeQL alert #3 (py/weak-sensitive-data-hashing).

- Fix validate.yml: was validating root-level files (now deleted); updated
  to validate custom_components/solar_of_things/ paths. Added integration_type
  and homeassistant to manifest required-key checks.

- Fix release.yml: was zipping from root-level files; updated to zip
  custom_components/solar_of_things/ correctly.

+- **Removed stale root-level duplicate files** (`__init__.py`, `api.py`, `config_flow.py`,
+  `const.py`, `sensor.py`, `number.py`, `select.py`, `switch.py`, `manifest.json`,
+  `strings.json`, `translations/`) — these were leftover copies from before the
+  v2.4.0 HACS restructure. They confused CodeQL (triggering duplicate alerts on
+  deleted code), could mislead HACS, and were dead code.
+- **GitHub Actions `permissions` hardened** — `validate.yml` and `codeql.yml` now
+  declare `permissions: contents: read` (principle of least privilege). Resolves
+  CodeQL alert #1 *(actions/missing-workflow-permissions)*.
+- **CodeQL workflow added** (`.github/workflows/codeql.yml`) — explicit weekly
+  security scan scoped to `custom_components/solar_of_things/` only, with a
+  documented exclusion for the protocol-mandated MD5 pre-hash.
+- **CodeQL config added** (`.github/codeql-config.yml`) — scopes analysis to the
+  integration source, ignores `dist/` and `tests/`, and documents the
+  `py/weak-sensitive-data-hashing` suppression rationale.
+- **MD5 suppression documented in source** (`api.py` line ~315) — added
+  `# noqa: S324` and an explanatory comment. The Siseli API rejects plaintext
+  passwords (returns error code 7); MD5(password) is a protocol requirement of
+  the upstream service transmitted over HTTPS. This is not password storage and
+  cannot be changed without breaking authentication.
+- **`validate.yml` fixed** — was still pointing at root-level `.py` files and
+  `manifest.json` (which no longer exist). Now correctly validates
+  `custom_components/solar_of_things/`. Added `integration_type` and
+  `homeassistant` to the manifest required-key check.
+- **`release.yml` fixed** — was building the ZIP from root-level files. Now zips
+  `custom_components/solar_of_things/` correctly.

-The integration supports two modes:
-
-  Email + Password (MODE_PASSWORD):
-    • api.login() is called at setup → obtains accessToken + refreshToken.
-    • _ensure_token_valid() is called before every API request; it proactively
-      refreshes the token 5 minutes before expiry using the refresh-token
-      endpoint, and falls back to re-login with stored credentials if the
-      refresh token is also expired.
-    • on_token_refreshed callback updates the config entry with fresh tokens so
-      the state survives HA restarts without having to re-login every time.
-
-  Legacy IOT-Token (MODE_TOKEN):
-    • The stored token is used as-is.
-    • On 401 / TokenExpiredError, the coordinator raises UpdateFailed and also
-      calls entry.async_start_reauth() so the user is prompted for a fresh token.

-
-Authentication strategy
-─────────────────────────────────────────────────────────────────────────────
-The Siseli portal uses a dual-token system.  Login requires the IOT Open
-Platform signing scheme discovered via JS bundle analysis (umi.js):
-
-  Endpoint : POST https://test.solar.siseli.com/apis/login/account
-  Signed   : yes — IOT-Open-AppID, IOT-Open-Nonce, IOT-Open-Body-Hash,
-                    IOT-Open-Sign headers
-
-Signing algorithm (reverse-engineered from portal umi.js):
-  1. Build a dict of signing headers:
-       {"IOT-Open-AppID": appId,
-        "IOT-Open-Body-Hash": sha256(body_bytes).lower(),
-        "IOT-Open-Nonce": random_32_char_hex}
-  2. Sort keys alphabetically, join as k1=v1&k2=v2 (no URL-encoding).
-  3. base64-encode the resulting string.
-  4. HMAC-SHA256(b64_str, decrypted_app_secret)  [bytes result]
-  5. MD5(hmac_bytes).hexdigest()  → IOT-Open-Sign value
-
-App secret decryption (qe() in umi.js):
-  key = MD5(appId).lower()[:16]  treated as ASCII bytes  (16 bytes = AES-128)
-  iv  = MD5(appId).lower()[16:]  treated as ASCII bytes  (16 bytes)
-  AES-128-CBC-ZeroPadding decrypt of base64(encrypted_secret)
-
-After successful login the server returns an accessToken (used as
-IOT-Token header for data requests) and a refreshToken.
-
-This class supports three auth modes, tried in priority order:
-
-  1. User-ID + password  (recommended)
-     • Call login() at startup → stores both tokens in memory.
-     • _ensure_token_valid() checks expiry before every API call and
-       proactively refreshes (TOKEN_REFRESH_LEAD_SECONDS = 5 min before
-       expiry, mirroring the portal JS behaviour).
-     • If refresh fails, raises TokenExpiredError so the HA integration
-       can trigger a re-auth flow.
-
-  2. Token-pair (accessToken + refreshToken) without password
-     • User pastes both tokens from DevTools.
-     • Same proactive-refresh logic; re-auth needed when refreshToken
-       expires.
-
-  3. Legacy IOT-token only (backwards compatibility)
-     • No refresh possible; raises TokenExpiredError on 401 so HA can
-       prompt the user to re-enter a fresh token.
-

-"""Config flow for Solar of Things integration.
-
-Supports two setup modes:
-  1. User-ID + Password  (recommended) – integration logs in automatically and
-     refreshes the token without any user intervention.
-  2. IOT Token (legacy / advanced) – user pastes the token from DevTools.
-     A re-auth flow is triggered when the token expires.
-
-Re-auth flow:  HA calls async_step_reauth when a TokenExpiredError is caught by
-the coordinator.  The user is asked only for the field(s) that need updating
-(usually just a fresh token, or new credentials).
