Subject: [PATCH] Remove legacy moderation overrides support

Removed the legacy support for version 1 moderation overrides in `js/state/cache.js`. This includes removing the `LEGACY_MODERATION_OVERRIDE_STORAGE_KEY`, the migration logic in `loadModerationOverridesFromStorage`, and the cleanup logic in `persistModerationOverridesToStorage`.
Updated `tests/state/cache.test.mjs` to include tests verifying that legacy overrides are ignored and not migrated.
