style(webapp): trigger review follow-ups — F4 comment, span-body indent, docs URL

idempotencyKeys.server.ts: reword 'bypasses the gate via F4' to 'bypasses the gate entirely' — last residual internal planning-label reference I missed in the earlier cleanup pass.

triggerTask.server.ts: reindent the startSpan arrow-function body to conventional depth (+4 sp on lines 143-619). The body was under-indented relative to the 'async (span) => {' opener after the try-wrapper for claim resolution was added around it; closes (arrow at 8sp, startSpan at 6sp) were already conventional, so only the body needed shifting. Pure whitespace — diff stat is balanced 413/413.

mollifierMollify.server.ts: docs URL → https://trigger.dev/docs/management/tasks/batch-trigger. The previous burst-handling anchor doesn't exist on the docs site.
