feat(shard): Protocol 2.0 cross-links — titles, guild, governor, houses

Phase 3: surface the new board data on existing character/user pages.

- Character sheet: render the char.profile titles block (fame/karma + skill +
  selected reward title; numeric clilocs skipped since the site has no cliloc
  table yet), plus "Guildmaster" and "Governor of <city>" chips.
- Char profile enrichment (player/admin /shard/char/:serial, one shared path):
  attach guild + governorOf from our own boards. Guild is LEADERSHIP-ONLY — it's
  verifiable from current board state, whereas guessing membership from stale
  guild.join events risks showing a wrong guild, so we return null instead.
- Admin user detail (/admin/users/:id): new "Standing" section (governorships
  held + guilds led) via GET /users/:id/shard/standing; Houses rows now show the
  registry fields (decay level, placement price, co-owner/friend counts) already
  returned by listHousesForAccounts.

Server 179/179, client build clean, swagger regenerated.
