feat(session): rank metadata in UserPermissions snapshot

Extend the `UserPermissionsEvent` parser and `IUserDataSnapshot` with
rank metadata mirrored from the Arcturus `permission_ranks` table:
rankId, rankName, rankBadge, rankPrefix, rankPrefixColor.

The new fields are appended to the wire payload AFTER the existing
[clubLevel, securityLevel, isAmbassador] triple. The parser guards
the trailing block with `if(!wrapper.bytesAvailable) return true;`
so older emulators (that don't write the extension) keep working —
the snapshot just exposes the defaults (rankId=0, empty strings) in
that case.

`SessionDataManager.onUserPermissionsEvent` stores the values; the
snapshot builder includes them; existing
`invalidateUserDataSnapshot()` semantics flow through unchanged, so
a runtime promote/demote (via `HabboManager.setRank` →
`UserPermissionsComposer`) auto-flips the React-side
`useUserRank()` / `useHasRankLevel()` / `useIsRank()` consumers in
the Nitro-V3 client.

Companion changes:
- Arcturus-Morningstar-Extended:
  `UserPermissionsComposer.composeInternal()` now appends the 5
  extra fields (pending operator commit; see
  ../Arcturus-Morningstar-Extended/Emulator/src/main/java/
  com/eu/habbo/messages/outgoing/users/UserPermissionsComposer.java).
- Nitro-V3:
  `useSessionSnapshots.ts` exposes the new family
  (useUserRank / useHasRankLevel / useIsRank), replacing the
  SecurityLevel-based wrappers (useIsModerator etc.) that hardcoded
  the renderer enum names — those don't match the operator's
  `permission_ranks.rank_name` column.

Verification: tsgo clean, vitest 138/138.
