The old refresh path called MibContactsClient.fetchContacts() per
profile, which greedily walked every page and stuffed the union into
the contacts cache in one shot. A user with several hundred or several
thousand MIB beneficiaries paid for N round-trips before the screen
could render, and the cache write encrypted the whole blob each time.
Introduces a paginator that streams contacts on demand:
* MibContactsClient.fetchContactsPage(session, start, count) — single
page; fetchContacts() now layers on top for callers that want all
pages.
* MibContactsPaginator — walks the user's MIB profiles serially under
the existing mibMutex, returning one page per nextPage() call.
Categories are accumulated across calls.
* HomeActivity.refreshContacts now requests just the first page
(default 30 contacts) per login. Subsequent pages arrive via
HomeActivity.loadMoreMibContacts(), which ContactsFragment fires
from a scroll listener when the user is within 5 rows of the end
of any tab. NEXT_PAGE_SIZE is 100 — matches the API's natural
page size.
* ContactsCache.appendContacts merges a new page into the cached
list (dedupe by benefNo) instead of overwriting. The first page
of a refresh still uses save() so deletions take effect.
* HomeViewModel exposes mibContactsLoading / mibContactsHasMore
so the fragment can show a loading footer (item_loading_footer)
on each contact tab while a page is in flight.
* ContactsAdapter grows a showLoadingFooter flag and a second view
type for the footer row.
Search remains client-side over the loaded set — results may be
partial until the user keeps scrolling. The MIB API supports
server-side search via the `search` parameter but wiring it in is a
separate change.
