chore(workspace): migrate to Rust edition 2024

- Set `edition = "2024"` in workspace root `Cargo.toml`
- Set `rust-version = "1.85"` in workspace root `Cargo.toml`
- Run `cargo fix --edition` across all workspace packages
- Replace `lazy_static!` with `std::sync::LazyLock` in `udp-tracker-core`
  and remove the `lazy_static` crate dependency
- Wrap `std::env::set_var` in `unsafe {}` with safety comment in integration tests
- Fix all new clippy denials triggered by edition 2024 and toolchain update:
  - `io_other_error`: use `io::Error::other(...)` throughout console CI helpers
  - `unnecessary_semicolon`: remove trailing `;` after match expressions in
    event handlers across `udp-tracker-core`, `http-tracker-core`,
    `udp-tracker-server`
  - `single_match_else`: convert nested match to `if let` in persistence
    benchmark DB probe helpers
  - `unnecessary_map_or`: use `is_none_or` in `src/app.rs`
  - `non_std_lazy_statics`: replace with `LazyLock`
  - `borrow_as_ptr`: use `&raw const` in repository tests
- Fix `located-error` doctest assertion for edition 2024 doctest bundle path
- Add `doctest` to `project-words.txt`
- Update issue spec: mark all acceptance criteria DONE, record manual
  verification evidence, update progress log and workflow checkpoints

All checks pass:
- `linter all` exits 0
- 954 tests pass (0 failures)
- `pre-commit.sh` exits 0
- No `rust-2024-compatibility` warnings in project source

Closes torrust#1778
