fix: account_name not showing on events page — stale Dexie cache + duplicate assignment

Two Svelte-side bugs causing account_name to always show 'Account Name Not Set':

1. ae_core__site.ts: background site_domain refresh only pushed cfg_json back
   into $ae_loc after a stale cache hit. Now also pushes account_name and
   account_code when the store holds a placeholder value.

2. +layout.ts: duplicate ae_loc_init['account_name'] assignment at line ~475
   was overwriting the correct one at line ~385 with a different fallback string
   ('Account Name Not Set' vs 'Ghost Account'). Removed the duplicate.

Also includes user-intentional changes during testing:
- events/+page.svelte: typo fix ('You access' -> 'Your access'); Pres Mgmt /
  Launcher / Badges / Leads buttons now gated on trusted_access && edit_mode
- events/+page.ts: event list limit 25 -> 7
- events/[event_id]/+page.svelte: user edit
