feat: add 7 Spector easy-win scenarios for Sprint 1

[RickWinter]

Wire up 7 new Spector test crate scenarios that the emitter already supports without code changes:

• authentication/noauth
• documentation
• encode/array
• parameters/query
• type/model/inheritance/recursive
• azure/client-generator-core/access
• azure/client-generator-core/client-default-value

3 of the original 10 planned scenarios need emitter work:

• type/union (basic) - non-discriminated unions not supported
• type/property/additional-properties - non-discriminated unions
• type/model/inheritance/nested-discriminator - name collision bug

Pull request overview

This PR adds 7 new Spector test crate scenarios to the typespec-rust emitter test suite. These are "easy-win" scenarios that the existing emitter already supports without code changes. The PR also notes 3 additional planned scenarios that still require emitter work (type/union, additional-properties, nested-discriminator).

Changes:

• Added 7 new generated Rust crate scenarios: authentication/noauth/union, documentation, encode/array, parameters/query, type/model/inheritance/recursive, azure/client-generator-core/access, and azure/client-generator-core/client-default-value.
• Registered the new crates in the workspace Cargo.toml, Cargo.lock, and the tspcompile.js build script.
• Uncommented previously-commented-out entries in tspcompile.js for spector_recursive and spector_access, and added a new comment for spector_nesteddisc as a future TODO.
