67074a7581 Harden server-side input validation and auth defaults (#18018)
## Summary

- **File storage (LocalDriver):** Add realpath resolution and symlink
rejection to `writeFile`, `downloadFile`, and `downloadFolder` — brings
them in line with the existing `readFile` protections. Includes unit
tests.
- **JWT:** Pin signing/verification to HS256 explicitly.
- **Auth:** Revoke active refresh tokens when a user changes their
password.
- **Logic functions:** Validate `handlerName` as a safe JS identifier at
both DTO and runtime level, preventing injection into the generated
runner script.
- **User entity:** Remove `passwordHash` from the GraphQL schema
(`@Field` decorator removed, column stays).
- **Query params:** Use `crypto.randomBytes` instead of `Math.random`
for SQL parameter name generation.
- **Exception filter:** Mirror the request `Origin` header instead of
sending `Access-Control-Allow-Origin: *`.

## Test plan

- [x] `local.driver.spec.ts` — writeFile rejects symlinks, downloadFile
rejects paths outside storage
- [ ] Verify JWT auth flow still works (login, token refresh)
- [ ] Verify password change invalidates existing sessions
- [ ] Verify logic function creation with valid/invalid handler names
- [ ] Verify file upload/download in dev environment
