fix(plugin-system): load/enable failures, atomic state files, pip lock, test-double parity (#645)

- load_plugin: an on_enable() that raises unregisters the instance, so the
  next load retries instead of returning True "already loaded".
- get_plugin_info: guard plugin.get_info(); one plugin raising no longer
  breaks /api/v3/plugins/installed.
- plugin_state.json and the operation history are written with
  atomic_write_text under their lock.
- plugin_loader: module-level lock serialises pip installs across the
  parallel startup loaders.
- store_manager._install_via_download: extract dir cleanup moved to finally.
- Test doubles: draw_image() warns (DeprecationWarning; the real
  DisplayManager has none), MockDisplayManager.draw_text accepts the real
  signature's optional params, VisualTestDisplayManager logs draw errors at
  WARNING.
- Docs/comments: compatibility.py method name, PluginState.LOADED meaning,
  brittle schema count, why _report_skip_once uses setdefault.
- Remove unused PluginOperationQueue.get_active_operations().

- `check_system_compatibility.sh` no longer reports installed packages as missing.
- A network failure fetching GitHub repo info logs a warning, not an error.
- Plugin system:
- A plugin whose `on_enable()` raises is no longer left registered: the next load retries it instead of reporting "already loaded" for a plugin that never ran.
- One plugin's `get_info()` raising no longer breaks the installed-plugins list; it is logged and shown with empty runtime info.
- `plugin_state.json` and the operation history are written atomically (temp file + rename) under their lock, so concurrent saves or a failed save can't leave a truncated file.
- Plugin dependency installs run one `pip` at a time during parallel startup loading.
- A failed store download no longer leaves its extraction directory in the temp dir.
- Test doubles: `draw_image()` on `MockDisplayManager`, `VisualTestDisplayManager` and `BoundsCheckingDisplayManager` now emits a `DeprecationWarning` — the real `DisplayManager` has no such method; use `display_manager.image.paste(img, (x, y))`. `MockDisplayManager.draw_text` accepts the real signature's `small_font`/`centered` and default `x`/`y`, and `VisualTestDisplayManager` logs draw errors at WARNING.
- Removed the unused `PluginOperationQueue.get_active_operations()`.
- Display runtime:
- Vegas comes back after live content interrupts it. It stayed paused, and the display fell back to normal rotation until a restart.
- A day with dimming turned off in a per-day dim schedule stays at normal brightness. Before, brightness went back to dim for most of each minute.
