Danny Avila bc8cef88ab 🛡️ feat: Generalize audit log into a tamper-evident, extensible event substrate
Reworks the SystemGrant-only audit log into a general-purpose, append-only
compliance substrate designed to absorb future event classes (agent runs,
tool/MCP calls, config + permission changes, approvals) without reshaping the
record. Nothing was shipped yet, so this replaces the grant-specific wire
shape rather than layering aliases.

Schema / record shape (packages/data-schemas):
- schemaVersion + two-level taxonomy: category + namespaced action
  (grant.assigned/grant.removed), first-class outcome and severity.
- Structured actor{type,id,name} supporting non-user actors (system, agent,
  service, schedule, webhook, api); generic target{type,id,name}; open
  metadata map; request context{requestId,ip,userAgent,sessionId}.

Tamper-evidence (hash chain):
- Per-tenant chain keyed by chainKey with seq/prevHash/hash. Appends link to
  the previous hash; a unique {chainKey,seq} index serializes concurrent
  writes (dup-key retry) so the chain can never fork. createdAt is explicit so
  it's covered by the hash.
- verifyAuditChain() walks a chain and detects modification, deletion, and
  forged links; exposed via GET /api/admin/audit-log/verify.

Other best-practice gaps from the review:
- Keyset (cursor) pagination over seq alongside offset; stable under
  concurrent appends. nextCursor in the page payload.
- Retention: purgeAuditLogEntries() privileged prefix-purge with a confirm
  latch, returns a checkpoint; verify tolerates a purged prefix.
- Fail-closed option (AUDIT_LOG_FAIL_CLOSED) so a failed audit write can fail
  the grant request instead of being swallowed; default stays fail-open.
- Grant handlers now capture request context and emit the new shape.

CSV export updated for the new columns (incl. seq/hash). data-schemas bumped
to 0.0.54 for the sibling admin-panel consumer. Tests rewritten: 28
methods-layer cases (chain genesis/linking, tamper detection, keyset, purge)
and the handler/grants specs updated for the new shape, fail-closed, and the
verify endpoint.
