Keep the empty-password account fix scoped to issue 17614

The first PR commit mixed SFTP file-manager credential changes with the authorized account flow. Restore SFTP-specific files and behavior to dev while retaining password and SSH-key input for hosted accounts without stored secrets. The original SFTP implementation remains available on the local wip/sftp-temporary-credentials branch for a separate submission.

Constraint: Issue jumpserver/jumpserver#17614 covers authorized empty-password account connections, not SFTP file-manager behavior
Rejected: Keep SFTP changes in this PR | they belong in a separate follow-up
Confidence: high
Scope-risk: moderate
Tested: 85 focused Vitest tests; pnpm test:web (995 passed, 14 skipped); pnpm typecheck:web; pnpm typecheck:electron; pnpm lint:check; git diff --cached --check
Not-tested: Web Proxy tests, per user request
