Sync ROADMAP statuses with landed work; mark 1.10/1.12/1.13 as paused

Tasks 1.1-1.9 marked done with their landing commit SHAs. Tasks 1.10
(observability), 1.12 (production hardening), and 1.13 (device
authority) marked paused with explicit resume triggers — pilot
deployment on real Teltonika hardware takes priority. Task 1.11
remains as next, in slimmed form for the pilot (no /readyz healthcheck
since the metrics endpoint is part of paused 1.10).
