perf: set global prisma transaction timeouts and reduce transaction scope (#2607)

Configure default transaction options (5s maxWait, 10s timeout) on the
PrismaClient instead of per-transaction overrides. Move side effects
like email sending, webhook triggers, and job dispatches out of
$transaction blocks to avoid holding database connections open during
network I/O.

Also extracts the direct template email into a background job and fixes
a bug where prisma was used instead of tx inside a transaction.
