Playtest #5 follow-up: boss-field blowers show in the normal rounds; 联防 timer restart confirmed

- act2 m01: the boss field's row-6 blower machines stand under the bench in the normal and 联防 views again
  (the user: "吹风机原版道中也该有"); the integration-QA filter (BOSS_WALL_ROW) is removed from the 3D and 2D
  boards, so every device on a built tile is drawn in every view, as the workstream had it
- 联防: a knocked-out operator's redeploy timer restarting in full is confirmed by the user ("进联防复活时间确实是
  重新算"); the [ASSUMED] tags in DESIGN §5.5 / §6.1 / §19.3, META §4 and unite.js say so
- DESIGN §19 intro / §19.7 and the docs-consistency assertions updated; 2595 unit tests, all render browser suites green
