v2.4.1: Revert NoizDNS Chrome changes, fix tunnel stability

NoizDNS:
- Revert Chrome page-load burst cover traffic to simple 1-query-per-5-15s
- Revert tunnel query EDNS0 from 1452 to 4096 and remove AD=1 flag
- Remove EDNS0 query padding and stealth MTU override
- Force-deadline KCP conn in Stop() for fast port release

Android:
- Add 5s grace period to ignore spurious network changes after connection
- Remove stealth mode query size override from UI
- Update Snowflake to v2.12.1

CLI:
- Remove --query-padding flag

Submodules:
- noizdns: reverted to stable pre-Chrome state
- dnstt-mobile: fast KCP shutdown
- dnstt: suppress closed-conn errors during shutdown
