feat: display campaign createdAt in UI card

Campaign card now shows created date/time next to char/encounter counts.
Lets DM tell newest campaign apart (replay tool creates many).

createdAt already set at campaign create (line 2174). Display renders
formatted: 'Jul 1, 2026, 16:32'.

replay-combat.js: campaign + encounter names now include timestamp
(new Date().toLocaleString) for easy identification.

WS collection push verified live (injected test campaigns appeared
without reload).
