Introduce rotation configuration constants for map image handling. Adds rotation options (0, 90, 180, 270) and dispatcher signal name.
Add SelectEntity to control map rotation per map_flag. Rotation value is persisted via RestoreEntity and stored in hass.data. Dispatcher signal notifies image entities when rotation changes.
Register SELECT platform and initialize rotation storage in hass.data. Add proper unload cleanup and reload behavior.
Implement backend image rotation using Pillow. Rotation is applied in async_add_executor_job to avoid blocking the event loop. Includes defensive validation and fallback handling.
Add English and German translations for map rotation select entity. Includes user-friendly labels for rotation options.
Add documentation for the per-map rotation select entity. Explains: - How to rotate maps (0/90/180/270) - Where to find the rotation select entity - That calibration points are rotated as well - That no reload is required Also clarifies usage with Xiaomi Vacuum Map Card.

Overview
This PR adds per-map rotation support to the Roborock Custom Map integration.
Instead of handling rotation in the frontend, this implementation introduces a
dedicated Select entity per map that allows users to rotate the map image
directly within Home Assistant.
What’s new
Why this approach
Frontend-only rotation (CSS/card-mod) rotates only the rendered pixels and
does not adjust calibration or interaction coordinates.
This implementation rotates:
so overlays and interactions (rooms, zones, taps) stay aligned.
