Refactor & improve public API

[Redm4x]

Improve public api

• Added swagger UI documentation
• Standardized endpoint urls (ex: /getMainnetVersion => /version/mainnet)
• Switched to honojs instead of express for a better dev experience (better typing + facilitate openapi definition)
• Added versioning to url and file structure to enable backward compatible upgrades (/v1/endpoint)
• Added eslint and improved typing across the board

Rename providers into services?

Does this new version of the API support the old routes? We should for a grace period of time because some clients use the API actively in their app and will break if we release without support.

Good point, I added legacyRouter.ts with redirects so that it doesn't break existing integrations. We should still contact those clients and point them to the new documentation so that they can switch to using v1
