Module app_data 

App-data plumbing for moving group state from group context extensions onto OpenMLS AppDataUpdate proposals.

This module is the bridge between the per-field intent handlers in mls_sync and the OpenMLS app data dictionary. It is intentionally pub(crate) — there is no public API for reading or writing arbitrary components. The existing per-field helpers (update_group_name, update_admin_list_action, …) keep their signatures and route through the appropriate sub-module here when the group has flipped proposals_enabled.
