Community browser: auto-refresh on open + longer relay timeouts

Three reported issues:

1. "When I click the button it should auto-refresh." The two Browse-
   Community buttons opened the modal and called switchModalTab('New'),
   which routes to loadFeedTab. fetchFeedAndReactions honours a 5-minute
   cache (line 16310), so a user reopening the browser within that
   window saw stale results — including not seeing their own design
   they just published. Add invalidateFeedCache() before opening the
   modal so the 5-minute cache is bypassed on every Browse click.
   Applied to both #browseCommunityBtn and #designerBrowseCommunityBtn.

2. "Sometimes it does not load everything in correctly each time."
   The relay fetch timeouts were tight enough that slow relays would
   miss reply windows. Bump:
     - templates: 4500ms → 6000ms
     - deletions: 3500ms → 5000ms
     - reactions: 2500ms → 4000ms
     - zap receipts: 4500ms → 6000ms
   Streaming via onEvent is unaffected, so the first event still
   appears the moment any relay responds; the longer ceiling just
   means more events make the cut before the await resolves.

3. "Zap and up-vote ranking is not working reliably." The sort logic
   in loadFeedTab is correct — Popular sorts by zap total, then
   reactions, then trust, then date; Zapped sorts purely by zap
   total. Reactions are fully fetched before the initial rerender;
   zap receipts stream in asynchronously and trigger debounced
   rerenders via scheduleZapStreamRerender → notifyFeedProgress,
   which re-sorts using the now-current _zapCache. So unreliable
   perception was mostly "I see initial sort, then it reorders."
   The fix here is indirect — longer zap timeout + auto-refresh on
   open mean more zaps arrive within the first rerender window, so
   the user sees the correct order sooner instead of watching it
   shuffle.
