Subject: [PATCH] fix(viewer): normalize mission IDs hash vs underscore +
 auto-switch USV tab

BUG3b: data-dates API returns hash prefix, missions API returns underscore.
Normalize both sides before comparing to properly filter mission fetches.
BUG1c: auto-switch to USV tab after sortie data loaded so charts are visible.
