Claude 94121c71c9 feat(cashu): mint URL directory + autocomplete ...

Adds a cache-backed Cashu mint directory sibling to LocalCache.relayHints
that aggregates mint URLs from every relevant event the cache sees, and
wires it into the AddCashuWallet mint-URL text field as inline
autocomplete so users don't have to remember mint URLs.

What feeds the directory:
- NutzapInfoEvent (kind:10019) — every nostr user with a Cashu wallet
  publishes their accepted mints there. A typical inbox of cached
  profiles seeds a useful starter directory automatically.
- MintRecommendationEvent (kind:38000) — explicit public vouches.
- CashuMintEvent (kind:38172) — formal mint announcements from the
  NIP-87 directory subscription.

How it's populated:
- LocalCache.updateMintIndex(event) is called from
  justConsumeAndUpdateIndexes alongside updateHintIndexes, so every new
  event with a mint URL adds to the index. wasNew gating prevents
  re-emissions from inflating popularity counters.
- LocalCache.ensureMintDirectoryBackfilled() does a one-shot scan of the
  existing notes + addressables maps. The autocomplete UI kicks this in
  a LaunchedEffect on screen open so suggestions are useful before the
  next relay round-trip.

Where it surfaces today:
- AddCashuWalletScreen — under the mint-URL OutlinedTextField, a
  MintSuggestionList card shows up to 6 cache-derived suggestions ranked
  by popularity desc + URL asc. Tapping a row fills the field (does not
  auto-add — users typically want to Verify first). Filters out URLs the
  user already added and exact matches of what they typed.

The MintPicker dropdown inside the Receive / Send dialogs is unchanged
— those only need to choose between mints the user already has in their
wallet, so no directory autocomplete applies there.

Tests: 8 unit tests cover normalisation (case-insensitive, trailing-slash
stripping, http(s) gating), popularity ranking, substring filtering,
limit enforcement, and malformed-URL handling.

URL normalisation: trimmed, lower-cased, trailing `/` stripped, scheme
must be http(s). Same URL with different casing or trailing slash
collapses to one entry so popularity counts correctly.

Implementation notes:
- MintDirectoryIndex lives in commons/jvmAndroid (uses ConcurrentHashMap;
  iOS doesn't ship Cashu wallet yet).
- Thread-safe; safe to read from any dispatcher.
- No persistence — purely in-memory, accumulates over the session.
- Entries are never removed: stale entries don't hurt (user always
  verifies before adding), and tracking which event added which URL
  would add bookkeeping without UX benefit.
