Three independent forms on /hosts/{id}/repo so saving one section
doesn't disturb the others:
* Connection: edits repo URL, username, password (pre-filled from
the redacted GET /api/hosts/{id}/repo-credentials view; password
field shows masked stored-creds placeholder; blank password = keep
existing). On save, encrypts and pushes config.update to a
connected agent.
* Bandwidth: host-wide upload/download caps (KB/s; blank = no cap)
written via store.SetHostBandwidth. New REST endpoint
PUT /api/hosts/{id}/bandwidth for JSON callers.
* Maintenance: forget/prune/check cadences + check subset %, with
per-row enabled toggles. Reuses cronParser for validation;
auto-seeds the row if a host pre-dates the migration.
Right-rail surfaces repo size, snapshot count, snapshots-by-tag
breakdown (counted from existing snapshot tag rows), and an
'untagged snapshots are left alone' note.
Danger-zone re-init button is rendered but disabled with a hint
pointing at P2R-09 (real implementation lands there).
Validation re-renders the page with the relevant form's banner and
all other section state intact. Successful saves redirect with a
?saved=<section> query param so the page surfaces a small ✓ saved
indicator on the relevant form.
ci.yml: bump golangci-lint-action v6→v7 (separate change picked up
in this commit).
