louispaulb aa5921481b feat: contract → chain → subscription → prorated invoice lifecycle + tech group claim
- contracts.js: built-in install chain fallback when no Flow Template matches
  on_contract_signed — every accepted contract now creates a master Issue +
  chained Dispatch Jobs (fiber_install template) so we never lose a signed
  contract to a missing flow config.
- acceptance.js: export createDeferredJobs + propagate assigned_group into
  Dispatch Job payload (was only in notes, not queryable).
- dispatch.js: chain-walk helpers (unblockDependents, _isChainTerminal,
  setJobStatusWithChain) + terminal-node detection that activates pending
  Service Subscriptions (En attente → Actif, start_date=tomorrow) and emits
  a prorated Sales Invoice covering tomorrow → EOM. Courtesy-day billing
  convention: activation day is free, first period starts next day.
- dispatch.js: fix Sales Invoice 417 by resolving company default income
  account (Ventes - T) and passing company + income_account on each item.
- dispatch.js: GET /dispatch/group-jobs + POST /dispatch/claim-job for tech
  self-assignment from the group queue; enriches with customer_name /
  service_location via per-job fetches since those fetch_from fields aren't
  queryable in list API.
- TechTasksPage.vue: redesigned mobile-first UI with progress arc, status
  chips, and new "Tâches du groupe" section showing claimable unassigned
  jobs with a "Prendre" CTA. Live updates via SSE job-claimed / job-unblocked.
- NetworkPage.vue + poller-control.js: poller toggle semantics flipped —
  green when enabled, red/gray when paused; explicit status chips for clarity.

E2E verified end-to-end: CTR-00007 → 4 chained jobs → claim → In Progress →
Completed walks chain → SUB-0000100002 activated (start=2026-04-24) →
SINV-2026-700012 prorata $9.32 (= 39.95 × 7/30).
