Renamed and refactored methods in `CookieNames` to improve naming consistency and simplify usage. Added overloads with default `defaultCookieName` set to `"AuthToken"`. Updated XML documentation to reflect these changes.
Updated `CookieNamesTests` to use the new method names and signatures. Adjusted test cases to align with the new default behavior and ensure compatibility.
These changes enhance code readability, reduce redundancy, and standardize method naming conventions.
Added a new `CookieNamesTests` class to validate methods in the
`CookieNames` class, including scenarios for generating and
extracting cookie names and keys. Tests cover valid, invalid,
and unrelated cookie names, as well as round-trip validation
of `GetEnvelopeReceiverCookieName` and `GetEnvelopeReceiverKeyOrDefault`.
Updated `DigitalData.Auth.Tests.csproj` to include a project
reference to `DigitalData.Auth.Claims` for testing purposes.
