fix(rust): the last fixes' small ones (W3 W6 W7/W11 W8 W10 W13-W18)

Stage 2 of PLAN_LAST_FIXES (docs#366).

- W7/W11: an "is it loaded" refusal is confirmed live before it is given.
  New liveStatus.js asks the sidecar once (boot.refreshOne, as a poll tick
  would), at most once per server per 5 s and waiting at most 3 s, then
  reads the stored status again. Used by Economics (step and staff page),
  Backpacks, Dangerous Treasures, Guarded Crate, RaidableBases, ZoneDomes,
  TruePVE and RunicNPC.
- W3: a world call answered `already-out` (the bridge half comes in stage
  3) succeeds as called 0, saying a Travelling Vendor is already out.
- W6: "A locked crate dropped by a Chinook is being hacked."
- W8: a RaidableBases profile's audit row names RaidableBases, not "@data".
- W10: the backpack sizes picker lists each size once, naming its servers.
- W13: a RaidableBases name both servers describe differently shows each
  server's own description.
- W14: each RaidableBases note after the first starts its own sentence.
- W15: a staff deposit refused at Economics' limit answers 409.
- W16: a payment's failedNote explains only the reasons that happened.
- W17: the sync state counts player grants that did not land
  (waitingToLand), and the Permissions page says "in sync · 1 waits for
  their player to join" instead of plain "in sync".
- W18: Guarded Crate's kept note drops the "30 minutes" it could not know.
