feat: job-level Est. completion in drawer header (1.0.0-53)

The drawer's per-stage Finish chip is the stage's finish, not the
whole burn-in's. Added a right-aligned "Est. completion" pill in
the drawer-job-header that uses the server-weighted burnin.percent
to extrapolate the whole job's finish time (covers precheck + SMART
+ surface_validate + final_check).

Suppressed under 0.5% job progress to avoid the early-sample
overshoot we saw earlier ("Finish: Sep 22" on a fresh start).

Bind-mount only (templates + static); no rebuild needed. Running
container reports 1.0.0-52 until next rebuild; this commit just
catches the source version up.
