fix: Handle email-style usernames in Coursier cache path credential stripping (#1538)

When a repository uses an email address as the username (e.g.,
user@domain.com), Coursier encodes the cache path as
"user%40domain.com%40host". The existing credential stripping logic
uses find("%40") which locates the first %40 (the email's @), leaving
"domain.com%40host" in the path instead of just "host".

This change:
- Replaces find("%40") with rfind("%40") to locate the last %40,
  which is always the user@host separator
- Extracts the stripping logic into a public
  strip_credentials_from_cache_path() function for testability
- Adds unit tests covering: no credentials, simple username, and
  email-style username cases
