feat(networks): extend the local http port band to 8107

PORT_BANDS.local.http (8001-8099) has no free port left: `cli contributing network ports suggest --scope local --category http --count 2` reports 0 free, so the custom web-app-cst-store role cannot take a host-bound port without colliding with web-app-hermes (8092) and web-app-openbao (8093). 8100-8107 are free as host-bound ports (web-app-bluesky uses 8100 only as an internal container port) and 8108 starts the typesense band, so the band now ends at 8107, the highest port that stays clear of it.
