fix: auto-repair missing plugins on startup (#293)

* fix: auto-repair missing plugins and graceful config fallback

Plugins whose directories are missing (failed update, migration, etc.)
now get automatically reinstalled from the store on startup. The config
endpoint no longer returns a hard 500 when a schema is unavailable —
it falls back to conservative key-name-based masking so the settings
page stays functional.

* fix: handle ledmatrix- prefix in plugin updates and reconciliation

The store registry uses unprefixed IDs (e.g., 'weather') while older
installs used prefixed config keys (e.g., 'ledmatrix-weather'). Both
update_plugin() and auto-repair now try the unprefixed ID as a fallback
when the prefixed one isn't found in the registry.

Also filters system config keys (schedule, display, etc.) from
reconciliation to avoid false positives.

* fix: address code review findings for plugin auto-repair

- Move backup-folder filter from _get_config_state to _get_disk_state
  where the artifact actually lives
- Run startup reconciliation in a background thread so requests aren't
  blocked by plugin reinstallation
- Set _reconciliation_done only after success so failures allow retries
- Replace print() with proper logger in reconciliation
- Wrap load_schema in try/except so exceptions fall through to
  conservative masking instead of 500
- Handle list values in _conservative_mask_config for nested secrets
- Remove duplicate import re

* fix: add thread-safe locking to PluginManager and fix reconciliation retry

PluginManager thread safety:
- Add RLock protecting plugin_manifests and plugin_directories
- Build scan results locally in _scan_directory_for_plugins, then update
  shared state under lock
- Protect reads in get_plugin_info, get_all_plugin_info,
  get_plugin_directory, get_plugin_display_modes, find_plugin_for_mode
- Protect manifest mutation in reload_plugin
- Prevents races between background reconciliation thread and request
  handlers reading plugin state

Reconciliation retry:
- Clear _reconciliation_started on exception so next request retries
- Check result.reconciliation_successful before marking done
- Reset _reconciliation_started on non-success results to allow retry
