list a user's own support tickets, Persian digits in completion notifications, rewrite .env.example to match the code

GET /api/support/tickets returns the caller's last 20 tickets with their
support-reply count, on the read throttle so listing never spends the
30/hour create quota. Before it the app kept ticket ids only in one
browser's localStorage, so a ticket and its answer vanished with the device.

Completion notifications now use Persian digits and drop the
'with 0 stars ... 0 points' sentence when nothing was earned.

.env.example: NUM_PROXIES=2 (ArvanCloud + nginx), KAVENEGAR_OTP_TEMPLATE,
BAZAAR_PISHKHAN_API_SECRET, sandbox off by default; removed variables the
code no longer reads.
