- Developer tools (send event, state event editor, room account data) and
setMarkedUnread go through the typed helpers in utils/room and
utils/accountData (new setRoomAccountData) instead of casting at the
call site; sendStateEvent accepts a developer-chosen type string.
- SecretStorage passes the key description as the SDK's
SecretStorageKeyDescription, CallEmbed replies with an IWidgetApiRequest,
and fillMissingPowers writes through a Record instead of `as any`.

Add centralized typed helpers in src/app/utils/accountData.ts:
- getAccountData<T>(mx, eventType): T | undefined (returns content)
- setAccountData<T>(mx, eventType, content): Promise<void>
These wrap the single `as any` cast needed because matrix-js-sdk's typed
overloads reject the fork's custom account-data event names. Every call site
now stays fully typed on its content shape.
Route all account-data reads/writes that previously used
`(mx as any).getAccountData/setAccountData` or `mx.getAccountData(... as any)`
through the helpers (or, where a MatrixEvent is needed, through the existing
utils/room.ts getAccountData whose param is widened to accept string keys).
No behavior change: same event types, same content shapes.
