perf(admin-web): relax template wizard assist poll cadence to 3s

Polling analyze/title/outline task results every 1.2s was over-eager
for AI tasks that typically run 15-30s. Bump interval to 3s and lower
max attempts to 40, extending total timeout from 72s to 120s while
roughly halving request volume.
