Add addons table

[jakubno]

• Add addons table
• Simplifies types for team, moves the querying to db and types to dedicated module, limits the usage of generated types

---

Note

Adds an addons table and shifts limit enforcement from Tier to aggregated TeamLimits across DB queries, types, auth cache, handlers, orchestrator, and template flows.

• Database:
  • Add public.addons table with RLS and indexes; create team_limits view aggregating tier + active addons.
  • Replace tier-based queries with team_limits joins; update SQLc code; remove old tier queries/files.
• Types:
  • Introduce internal/db/types: Team, TeamLimits, TeamWithDefault and constructors.
  • API now passes *types.Team (with Limits) instead of queries.Team/Tier pairs.
• Auth/Cache:
  • Auth cache stores and returns *types.Team; validation function signatures updated.
• Handlers/Orchestrator:
  • All endpoints use *types.Team; enforce limits via team.Limits (concurrency, max hours, vCPU/RAM/disk).
  • Rename helpers: GetTeamAndTier -> GetTeamAndLimits; analytics/telemetry use new team fields.
• Template builds:
  • Concurrency gating uses Team.Limits.BuildConcurrency; resource limiting uses team.Limits.
• Models (ent):
  • Remove Tier model/edges and related generated code; adjust Team schema/edges accordingly.
