[decompose] extract ProfileHashtagController from js/ui/profileModalController.js

Extracts all hashtag preference related logic into a new controller
`js/ui/profileModal/ProfileHashtagController.js` to reduce the size of `js/ui/profileModalController.js` and improve maintainability.

- Moves `normalizeHashtagTag`, `formatHashtagTag`, `getResolvedHashtagPreferences`, `setHashtagStatus`, `refreshHashtagBackgroundStatus`, `populateHashtagPreferences`, `renderHashtagList`, `sanitizeHashtagList`, `createHashtagListItem`, `persistHashtagPreferences`, `handleAddHashtagPreference`, `handleRemoveHashtagPreference`, `handleHashtagPreferencesChange`, `describeHashtagPreferencesError`.
- Updates `ProfileModalController` to delegate to `ProfileHashtagController`.
- Adds delegate getters/methods in `ProfileModalController` to maintain backward compatibility for tests.
- Reduces `js/ui/profileModalController.js` by ~600 lines.
- Updates file size baseline in `scripts/check-file-size.mjs`.

Passes `npm run lint` and `npm run test:unit`.
