* Clean up worker-sandbox
- Remove unexpected fields from wrangler.toml (type, miniflare, package)
- Address or add allow rules for clippy::pedantic lints
- Add macros to avoid duplicate route configurations
- Move files from src/test/* to src/ and add test handlers and routes to
make it possible to run the tests from the sandbox worker
- Move several handlers out of alarm.rs and into more suitable files
(e.g., counter.rs where the corresponding Durable Objects live). Note
that the SHARED_COUNTER Durable Object class is still not yet defined.
- Fix and add test handler for handle_basic_test, which passes
except for the transactional storage API tests
* Address review comments
- Clean up additional clippy lints rather than add exceptions
- Describe how to get tests to pass even with dwarf-debug-info enabled
* Fix new clippy complaints
