feat: add encrypted room cache panel with load/load-more buttons

Each encrypted room in scope shows:
- Message count and oldest cached date
- 'Load messages' if no cache, 'Load more' if more history available
- 'Fully cached' label when all history is loaded

Clicking load/load-more paginates backwards 100 messages at a time.
localResult re-computes via cacheVersion after each load so search
results update automatically without re-typing the query.
