v2.3.2: fix fetch_settings alias + add missing set_* control methods

- api.py: add fetch_settings = get_device_settings class alias
- api.py: add set_operating_mode, set_battery_priority, set_grid_charging,
          set_grid_feed_in, set_backup_mode as update_device_settings wrappers
- manifest.json: version 2.3.2
- CHANGELOG.md: document fixes

These methods were called by __init__.py (fetch_settings), select.py, and
switch.py but did not exist on SolarOfThingsAPI, causing AttributeError on
every coordinator update.

+### Fixed
+- **`fetch_settings` AttributeError** -- `__init__.py` called `api.fetch_settings()`
+  but `api.py` only exposed `get_device_settings()`. Added `fetch_settings` as a
+  class-level alias so both names work.
+- **Missing control helper methods** -- `select.py` and `switch.py` called five
+  methods that did not exist on `SolarOfThingsAPI`:
+  `set_operating_mode`, `set_battery_priority`, `set_grid_charging`,
+  `set_grid_feed_in`, `set_backup_mode`. All five are now implemented as thin
+  wrappers over `update_device_settings`.
