ci fixes: cargo fmt, eslint entities, max-lines split

CI on 6ffbe97 failed on two auto-fixable gates. Both fixed:

  * cargo fmt --all — rustfmt applied across the surface touched
    by the last ~20 commits (world.rs, security_scan.rs,
    routes/{missions,nodes,terminal}.rs, fleet_herdr.rs,
    mission_workspace.rs, benchmark_runner.rs, mission_refiner.rs,
    lib.rs, tests/mission_orchestrator.rs, cm-db/repo/{missions,teams}.rs,
    bins/clawmates-node/src/main.rs)
  * eslint apostrophe escapes in HerdrSessions + MissionWizard
  * eslint max-lines: extracted EditMissionModal + RefineDiffModal
    (each ~200 LoC) into their own files. MissionCanvas drops from
    1424 to 1026, comfortably under both the 1250 eslint cap and the
    1500 CI budget.

New files:
  frontend/src/components/dashboard/EditMissionModal.tsx  (211 LoC)
  frontend/src/components/dashboard/RefineDiffModal.tsx   (208 LoC)

Verified locally: cargo fmt --check clean, cargo check clean,
mission_orchestrator test 3/3 pass, tsc + eslint --quiet both silent.
