Modify fallback stability requirements
Increase the fallback stability requirement to 30 days.
When this was at 7 days, we chose far too many unstable fallbacks.
Decrease the guard flag requirement to 0.8.
When this was at 0.9, we lost too many fallbacks due to version upgrades.
(The running and v2dir flags ensure DirPorts are available to clients.)
Partial fixes to #20913.
