chore: Convert to Tokio + Reqwest

[dbanty]

Enable future parallel requests and standard retry policy libraries

[Copilot]

Pull request overview

This PR migrates Knope’s networked integrations from ureq to async reqwest and introduces a Tokio runtime entrypoint, enabling future concurrent HTTP operations and reuse of standard async retry/middleware patterns.

Changes:

• Converted workflow/step execution to async and switched CLI entrypoint to #[tokio::main].
• Replaced ureq usage across GitHub/Gitea/Jira integrations with reqwest, adding a shared HTTP helper module.
• Updated dependency configuration (reqwest, tokio) and cargo-deny duplicate-skip rules accordingly.

@copilot please make a new PR which adds some integration tests for these services since changing them all seems risky. Assume I can create repos/accounts for testing and will provide required tokens/credentials in CI only. Don't make these tests run by default, only in their own CI job/context where I can put the secrets.

You can choose what is easiest from:

1. Writing integration tests in Rust, potentially using some of the helpers from existing tests
2. Writing tests in Python to better coordinate with checking results from external services
3. Scripting the tests with nushell if it would be less code / easier to maintain

Make sure to provide in that PR instructions on how to set up the required repos/accounts for the tests.
