feat: Avail gas relay upgrade (#3601)

## What ❔

This PR upgrades Avail Turbo DA from v0.1 to v1 with significant API
changes and improvements to the authentication system. The upgrade
includes a complete overhaul of the API endpoints structure,
authentication mechanism (moving from JWT to API keys), and internal
architecture improvements.

## Why ❔

Improve security through better API key management and support for
multiple keys per user
Enhance performance with better latency and higher throughput
capabilities
Create a more maintainable and extensible codebase through modular
design
Establish proper API versioning to better manage future updates and
backwards compatibility
Standardize endpoint structures by removing redundant path segments

## Is this a breaking change?
- [ ] Yes
