The "safe to drop legacy key" badge hardcoded bg-emerald-600/text-white. Swap it
for the success token (border-success/bg-success/text-success) the rest of the
settings surfaces use, so it tracks the theme.
Add a read-only admin Encryption section that surfaces what the rotation
tooling computes: per encrypted-column rows-per-key-id, legacy-key row
counts, and overall rotation progress, plus a 'safe to drop the legacy
key' state once every column sits on the active key. GET
/api/admin/encryption/status drives it and returns only key ids and
counts — never key material. A shared scan over the canonical encrypted-
column registry backs both this view and the rotation run. Cookie-only
admin.
