Subject: [PATCH] fix(api): Unescape literal characters in generated API URL
 types

The generator copied a route regex's escapes into the TypeScript union, so a route matching a
literal dot, like \.git, came out as '$repositoryId\.git'. oxlint rejects that string as a useless
escape. Escaped punctuation is now written as the character itself.
