Jakob Wennberg 6be6510d73 fix(entitlements): gate paid AI document OCR server-side (free-tier leak) (#852)
* fix(entitlements): gate paid AI document OCR server-side (free-tier leak)

Free/manual-tier companies could trigger paid Bedrock OCR (extractInvoiceFields)
with no `ai` capability check, on every transport:
- invoice-inbox HTTP paths — /upload + email /inbound (shared uploadAndExtract),
  /items/:id/attach-document, /items/:id/retry-extraction (4 call sites, zero
  capability refs);
- the gnubok_upload_document MCP tool — absent from MCP_TOOL_CAPABILITY_MAP, so a
  free-tier API key (incl. the claude.ai connector's minted gnubok_sk_ key) got
  unlimited AI extraction. This disproved the keys.ts "no MCP tool invokes AI"
  comment.

Fix (money-blocker for the free/paid tier cutover):
- Gate the 3 inbox call sites on hasCapability(CAPABILITY.ai). Upload + attach
  degrade gracefully (document still stored; extraction skipped with reason
  `no_ai_entitlement`, highest priority in the existing skipReason chain). Retry
  is an explicit "run AI now" action, so it hard-blocks with 403
  capabilityBlockedResponse.
- Register gnubok_upload_document -> CAPABILITY.ai in MCP_TOOL_CAPABILITY_MAP; the
  dispatcher already enforces the map. Correct the stale keys.ts comment and the
  misleading "deterministic field extraction" tool description + manifest copy
  (the extension migrated regex -> AI OCR).

Tests: no-AI upload/attach skip + retry 403 (sandbox-skip-extraction), retry 403
(retry-extraction), and the MCP map contract + refined dispatch<->commit parity
(capability-maps: upload_document is dispatch-only, no commit counterpart).

Self-hosted stays all-on (hasCapability short-circuits). No migration.
Follow-up (not in scope): capability-blind DashboardNav (free/paid rails identical)
and /chat gated on isVerified not `ai` — see dev_docs/nav_ia_redesign.md Part 4.

* test(mcp): assert gnubok_upload_document is ai-gated at dispatch

The gnubok_upload_document handler runs extractInvoiceFields (Bedrock OCR)
inline rather than through the entitlement-gated uploadAndExtract, so the
central MCP_TOOL_CAPABILITY_MAP dispatch check is the only paywall on that
transport. Lock it with a test (flagged by PR review as an untested money
path) so a free-tier connector key can never reach paid OCR.
