Add public playtime policy and lookup APIs

[remdui]

Summary

Adds the authoritative DataRegistry contract for the player-facing Playtime feature.

• blocks physical backend patterns before server-to-gamemode mapping or unknown-server fallback
• adds public query-blacklist policy separately from accrual and network-total policy
• exposes immutable playtime catalog metadata and direct UUID/identifier snapshot lookups
• applies one visibility policy to snapshots, profiles, tracked totals, leaderboards, and tracked-key discovery
• preserves configured playtime lists and server rules in canonical config output
• bumps the API/runtime version to 1.14.0

Configuration

playtime:
  blacklisted-server-patterns: []
  ignored-gamemodes: []
  query-blacklisted-gamemodes: []
  excluded-from-network-total-gamemodes: []
  server-gamemode-rules: []

• blacklisted-server-patterns: matching physical servers never accrue playtime. Evaluated before mapping and fallback.
• ignored-gamemodes: do not accrue and are omitted from public reads, including retained historical rows.
• query-blacklisted-gamemodes: remain internally tracked but are omitted from every public playtime read and total.
• excluded-from-network-total-gamemodes: remain queryable but do not count toward networkTotalMillis.

Physical blacklist changes are prospective. Historical time already aggregated into a shared logical gamemode cannot be split by physical backend.

Public API

• adds PlaytimeCatalog and PlaytimeGamemodeDefinition
• adds PlayerData#playtimeCatalog()
• adds UUID, PlayerLookup, and identifier playtime lookups
• keeps the existing player-ID/as-of and leaderboard methods
• resolves production identifier lookups and snapshots in one DataRegistry transaction

Consumers should use PlayerPlaytimeSnapshot#networkTotalMillis() as the canonical global value.

Compatibility

• no database migration
• existing aggregate and segment schema remains unchanged
• existing PlayerData playtime methods remain available
• release version bumped to 1.14.0
