fix: trim whitespace in redirect from and to

Redirects silently failed to match when a leading/trailing space was
present in the address (e.g. `to = " https://example.com"`), which is a
common typo that is hard to spot. Trimming the values in the redirect
normalizer resolves the issue while preserving the parsed rule shape.

Fixes #4707
