feat(php-shim): model $_ENV/$_SERVER as OsString snapshots

Rework the environment shim around getenv/putenv on the real environment
and $_ENV/$_SERVER as startup snapshots, all over OsString. Migrate every
caller off the old server()/server_argv() helpers and force the snapshots
in main() before any putenv() runs. Document the porting rules in
docs/dev/env-vars-porting.md.
