feat(primitives): move AnnouncePolicy from configuration to primitives (#1795)

[josecelano]

Summary

Moves AnnouncePolicy from torrust-tracker-configuration into torrust-tracker-primitives, fixing an inverted dependency where a primitives package depended on a configuration package.

• Before: primitives → configuration (for AnnouncePolicy)
• After: configuration → primitives (natural direction)

Changes

• Move AnnouncePolicy struct + impls into packages/primitives/src/announce.rs
• Export AnnouncePolicy from torrust_tracker_primitives lib.rs
• Remove torrust-tracker-configuration dep from primitives/Cargo.toml
• Add torrust-tracker-primitives dep to configuration/Cargo.toml
• Replace AnnouncePolicy definition in configuration/src/lib.rs with a #[deprecated] re-export for external consumer backwards compatibility
• Update configuration/src/v2_0_0/core.rs to import from torrust_tracker_primitives
• Update bittorrent-http-tracker-protocol test import + remove unused torrust-tracker-configuration dep from its Cargo.toml
• Update bittorrent-tracker-core integration test import
• Update announce_handler.rs doc comment import path

Verification

• cargo build --workspace: clean
• cargo test --workspace: all pass
• linter all: exit code 0
• cargo machete: no unused deps

Closes #1795
Part of #1669 (SI-04)

Pull request overview

Moves AnnouncePolicy from torrust-tracker-configuration to torrust-tracker-primitives to fix an inverted dependency where primitives depended on configuration. A #[deprecated] re-export is kept in configuration for external backwards compatibility.

Changes:

• Moved AnnouncePolicy struct + impls into packages/primitives/src/announce.rs and exported from primitives/lib.rs.
• Flipped the dependency direction: removed torrust-tracker-configuration from primitives/Cargo.toml, added torrust-tracker-primitives to configuration/Cargo.toml, and dropped configuration from http-protocol/Cargo.toml.
• Updated all in-workspace imports (configuration/v2_0_0/core.rs, tracker-core integration test, http-protocol test, and a doc-comment in announce_handler.rs) and updated spec/EPIC docs.
