fix(inputs): centralize admission and preserve caller selections

Move shared request parsing into its application owner, migrate all consumers, and remove six duplicated admission blocks while preserving cancellation and validation policy.

Keep operator-selected JavaScript paths in verifier parent Evidence while retaining canonical comparison guards. Validated with 204 passing tests, 3 Linux-x64-only skips, typecheck, lint, and test discovery.
