refactor(api): align v1 namespace and move conversion tests #1959

[josecelano]

Description

Implements SI-7 (#1959) - Review tests and align v1 namespace across REST API packages.

Part A: Move misplaced tests

• Moved conversion unit tests from axum-rest-api-server to rest-api-runtime-adapter::v1::conversion (tests belong with the production code they exercise)
• Added torrust-clock as dev-dependency to rest-api-runtime-adapter
• Removed empty peer.rs stub (only doc comment, no code)
• Cleaned up resources/mod.rs module declaration

Part B: Align v1 namespace

• Added v1/ module to rest-api-application, moved ports/ and use_cases/ under it
• Added v1/ module to rest-api-runtime-adapter, moved adapters/, container.rs, conversion.rs under it
• Updated all internal crate:: paths
• Updated all cross-package imports across the workspace

Verification

• cargo check --workspace ✅
• cargo test -p torrust-tracker-rest-api-runtime-adapter ✅ (2 tests pass)
• cargo test -p torrust-tracker-axum-rest-api-server --lib ✅ (1 test passes)
• cargo check --tests --workspace ✅

Now all 5 REST API packages consistently use v1/ module namespace:

Package	v1 module
rest-api-protocol	✅ v1/
rest-api-application	✅ v1/ (new)
rest-api-runtime-adapter	✅ v1/ (new)
axum-rest-api-server	✅ v1/
rest-api-client	✅ v1/

Pull request overview

Refactors the REST API workspace crates to consistently expose a v1 module namespace and relocates conversion unit tests to the crate that owns the conversion logic (rest-api-runtime-adapter), aligning package boundaries with the contract-first migration work in #1959.

Changes:

• Moved domain→protocol conversion unit tests from axum-rest-api-server into rest-api-runtime-adapter::v1::conversion, adding torrust-clock as a dev-dependency where needed.
• Introduced a v1/ module namespace in rest-api-application and rest-api-runtime-adapter, and updated all internal/cross-crate imports accordingly.
• Removed the empty peer.rs stub module and cleaned up the torrent resources module declarations.
