`/v1/evm/swaps` naming using latest DEX database

[DenisCarriere]

Calls only exists in Extended Block, the latest EVM DEX substreams v0.2.0 only uses Logs (not calls) to extract it's data.

Current way to implement :

/v1/evm/swaps

• caller uses trx_from

  we don't have this concept on SVM, we could call it signer "the account signing the transaction"

• sender uses user

  eventually should be renamed to user to align with SVM syntax

• recipient uses user

  eventually this field should be dropped, no concept of recipient on SVM

When we want to introduce breaking changes in:

/v2/evm/swaps

• ✅ new field signer (uses trx_from)
• ⚠️ renamed sender to user
• ❌ remove recipient field

The V2 would align more with SVM

Note: there could be other changes we introduce in V2 to align better with SVM swaps
