Routine dependency maintenance.
- Pin a few high-fanout transitive deps to current patched versions via
`pnpm.overrides`: `form-data`, `ws`, `undici`, `hono`. Lockfile-only (no
published-package dependency changes); net shrinks via dedup.
- Upgrade `nodemailer` 8 → 9 in `internal-packages/emails` (private
package). The SES transport already uses SESv2 and the
`createTransport`/`sendMail` API is unchanged, so no code changes were
needed. `@types/nodemailer` stays at 8 (no 9.x published yet; types are
compatible).
Verified locally: `pnpm i` clean; `pnpm run typecheck --filter emails`
and `--filter webapp` both pass.
