security: harden agent surface — vault_exec allow-list, SSRF, error hygiene

Stress-test remediation across MCP, CLI, and backend:

- primora_vault_exec rewritten as an allow-list (was deny-list):
  colon-form single-token commands bypassed it, leaking every vault
  secret; verbatim env-name injection allowed NODE_OPTIONS=--require
  host RCE. Now fixed read-mostly command set, arg/path deny regex,
  strict env-name grammar, loader-hook name blocklist. All prior
  bypasses verified denied; allowed commands still inject.
- SSRF: webhook/job URL validation now blocks cloud metadata IPs
  (169.254.169.254, fd00:ec2::254) inside the link-local allowance
  and non-canonical IP encodings (decimal/hex bare hosts) smuggled
  as "docker service names".
- Path params encodeURIComponent in all client consumers — encodeURI
  left ?#& intact, smuggling query segments through {name} params.
- primora_upload_object strict-validates contentBase64 — Buffer.from
  silently dropped invalid chars.
- MCP no-creds startup degrades instead of crashing mid-handshake.
- GET /api/v1/context — API-key self-discovery; fixes the CLI dead
  end (login --api-key validates the key + seeds org/project,
  use/context/whoami work under key auth).
- CLI: unknown commands / bare group exit 1 with hints; mri numeric
  coercion reversed via raw-argv restore (007 stays "007");
  login --json; orgs:rm / projects:rm / buckets:rm behind --yes;
  fetch-failed errors name the cause.
- Error hygiene: pgx.ErrNoRows -> 404, pgconn codes -> clean
  400/409 without SQLSTATE leaks, validator failures formatted,
  services.InputError maps input faults to 400 (webhook URL/event
  errors were 500s), presign on local driver -> 400.
- Webhook events accept wildcard patterns (*, ns.*, custom.*)
  matched via SQL LIKE — client-published events can be webhooked.
