fix: let FSR3 settings persist across restarts without env var

Browse source 
FSR2/FSR3 upscaling mode was forcibly reverted to FSR1 on every startup
unless the WOWEE_ALLOW_STARTUP_FSR2 environment variable was set. This
meant users had to re-select FSR 3.x and re-enable frame generation on
every launch. Removed the env var requirement since the deferred
activation (wait until IN_WORLD state) already provides sufficient
startup safety by preventing FSR init during login/character screens.
