* Add router.link.v1 config type. Fixes#3974
- adds the built-in `router.link.v1` ConfigType with a JSON schema
covering listeners, dialers, heartbeats, payload/ack sender queue
sizes, and `gcMode` for auto-GC of stale links
- targets routers (`Target=router`) via the field added in #3743
- registers it for new databases via `createConfigType` in
`initialize`, and for existing databases via a migration step that
bumps the schema version 46 -> 47
- adds config-type-store tests covering registration, the router
target, and migration-driven creation on existing databases
- documents the Phase 1c step in the controller-managed router
configuration design doc
* Address review feedback on router.link.v1 config type. For #3974
- broadens the duration schema pattern to accept compound and fractional values (e.g. 1h30m, 1.5h) matching time.ParseDuration
- adds the gcMode schema property (enum preserve/orphaned/changed) to the built-in config type so its definition is complete where the type is created
- adds duration-format and gcMode validation test cases
- removes the now-unnecessary per-iteration loop variable copy in the reject-cases test
