Pull request overview

This PR adds a new TVL (Total Value Locked) endpoint for DefiLlama integration to the Althea info server. The implementation calculates TVL by querying token supplies from the Cosmos bank module and accounting for escrowed amounts in IBC channels.

Key changes:

• New /unpriced_tvl endpoint that calculates TVL for Althea native tokens, IBC bridged tokens, and Althea L1-native ERC20s
• Token configuration module with support for multiple tokens (ALTHEA, USDC, USDT, USDS, sUSDS, GRAV, WETH)
• Refactored endpoint handlers into a dedicated module for better organization
