Operators can accept known-benign findings once and have Sencho filter
them out of scan drawers, comparison views, and other read surfaces.
Suppressions replicate from the control instance to every remote node.
* New cve_suppressions table with a COALESCE-based unique index so NULL
scope slots collide the way users expect
* Admin + paid-tier CRUD routes; writes are rejected on replicas
* Read-time filter enriches vulnerability details and compare payloads
without mutating stored counts
* Settings > Security panel for managing rules, per-CVE suppress action
in the scan drawer, dimmed rows with a shield-off indicator
* Vitest unit tests for the filter (glob, expiry, specificity) and
route tests (auth, tier, replica, UNIQUE conflict)
Scan policies now propagate from the control Sencho instance to every
registered remote. The control is the source of truth; replicas render
rules read-only with a managed-by-control banner. Pushes fire on every
policy write, record per-node success and failure on a new
fleet_sync_status table, and use node_proxy Bearer tokens exclusively
so only sibling Senchos can apply incoming sync payloads. Policy scope
now travels as a string identity (api_url or a local sentinel) so
node-scoped rules evaluate correctly on each target.
