chore(ci): add \validate:all\ + fix undefined \validate:monorepo\ reference

\`ci.yml\` had a \`pnpm run validate:monorepo\` step that referenced a
script defined nowhere in the repo — CI would fail at that step
whenever the validate job ran. Replacing it with a new bundled
\`validate:all\` script closes that gap and gives contributors a single
local command that mirrors what CI enforces.

- New \`validate:all\` chains the three fast repo-invariant checks
  (turbo recursion, pgSchema isolation, crypto registry) with fail-fast
  semantics. Runtime ~1s — suitable as a pre-push gate.
- \`validate:dockerfiles\` intentionally left out: its current output
  is 41 pre-existing "MISSING" warnings on two web Dockerfiles, which
  look like a validator-vs-wildcard-COPY mismatch rather than real
  issues. Keeping it as a standalone script so those can be
  triaged separately without blocking \`validate:all\`.
- ci.yml: four separate validate steps collapsed into one. The step
  rename also removes the dead \`validate:monorepo\` call.

Verified: \`pnpm run validate:all\` exits 0 in ~1s — 138 packages
scanned for turbo recursion, 727 TypeScript files for raw pgTable,
190 Dexie tables classified in the crypto registry (85 encrypted,
105 allowlisted plaintext).
