P1 security batch: quota execution checks, cost accounting, goal/coordinator semantics, PR channel, orphan signature, control-plane and console hardening

- Docker quota watchdog + fail-closed quota checks, system tasks need real owner
- max_cost_usd actually accumulated, cancel records cost, estimated rows excluded from unpriced cap, cache_write declared non-billed
- goal-resume keeps original verify on breakpoint resume, goal retry falls back to resume, goal_max_rounds capped at 100 at create and execution
- coordinator children inherit parent model/effort, orphans marked interrupted with audit
- PR jobs on docker workers return explicit needs_local_worker instead of silent empty
- worker code signature covers 6 files and is checked before claim, fail-closed
- sub2api lazy provisioning with rotation, backup whitelist + 0600, push SSRF block, repos/workers desensitized, key/project audits and limits, console buttons/quota/status wording, coordinator/automation quota reserve
