Add drafts & feedback tab to case page, remove global feedback page

Move draft management (export DOCX, download, upload revised version, mark
final) and chair feedback into a new "טיוטות והערות" tab on the case detail
page. Remove the standalone /feedback page and its nav link since feedback
is now case-scoped.

Also fix /api/admin/skills 500 error when Paperclip DB is unreachable by
adding a connection timeout and graceful fallback to disk-only skills.
