Add a field filter type reading any payload value by JSONPath with array expansion, 12 comparison operators (eq/ne/contains/startsWith/endsWith/regex/gt/gte/lt/lte/in/exists), a visual AST builder (all/any/not) in the route editor, chip-based multi-value input, a stateless POST /admin/api/test-match dry-run, and named filter fragments stored in D1 (d1_fragments, migration 0010) inlined into route ASTs on insert.
- apiFetch + shared needLogin (any 401 shows the login card) replaces six
duplicated fetch/401/error-handling blocks in the admin composables
- useCopy composable: clipboard + execCommand fallback with timed reset,
used by MembersPanel and WebhookPanel
- utils/format.ts (fmtTime/splitList/parseMatch) removes inline duplicates
across SendLogs, AuditLog, RouteEditor and GroupEditor
- fix: load the audit log when the audit tab becomes active (client-side
navigation never remounted the page, leaving the list empty on first visit)
- fix: fetch the real route count for a group before confirming deletion
instead of reusing the currently open group's route list
