feat: migrate from Gin to Echo framework
- Migrated from Gin to Echo framework to improve performance and routing capabilities. - Updated `go.mod` and `go.sum` to include Echo and its dependencies. - Refactored route definitions and handlers to use Echo's API. - Improved error handling and assertions in test cases using Testify. - Introduced middleware for host-based routing with secure handling for unknown hosts.
