Session work 2026-05-04: Grabb Leap calendar fix, Dataforth lobby phone VLAN, IMC printer + VPN

- Grabb & Durando: investigated and resolved Svetlana Larionova's Leap-to-M365 calendar OAuth consent issue (Graph-side report + session log). Syncro #32245.
- Dataforth: lobby phone (ext 201) was offline due to D1-Server-Room port 1 being on the wrong VLAN; reconfigured to VLAN 100, phone re-provisioned and registered. Session log + PROJECT_STATE update. Syncro #32246.
- Instrumental Music Center: Station 2 receipt printer reconnect + VPN install on Manda's machine. Syncro #32247.
- Memory: generalized the Syncro blank-contact rule (was Cascades-only) and added the labor-type rule (never use "Prepaid project labor") per Winter's 2026-05-04 corrections.
- Gitignored `.claude/tmp/` so per-session helper scripts don't sneak in.
