feat(evm): add "eth.evm.v1.MsgConvertEvmToCoin" tx for ERC20 to bank coin conversions with a non-Ethereum transaction (#2345)

* feat: add convertEvmToCoin

* chore: changelog

* feat: revert gitignore changes

* Update x/evm/keeper/msg_server.go

Co-authored-by: Copilot <[email protected]>

* Revert "Update x/evm/keeper/msg_server.go"

This reverts commit 335862b.

* fix: lint

* refactor: lint, fmt, and name consistency with FunToken type

* docs(CHANGELOG): slightly more descriptive changelog entry

* fix: revert version update to golangci-lint back to v6

* docs(changelog): typos in URLs

* fix(evm): remove ERC20 approval requirement by switching from transferFrom to transfer

This change simplifies the `ConvertEvmToCoin` flow for ERC20-originated tokens
by replacing the use of `transferFrom` with `transfer`. As a result, token
approvals are no longer needed prior to conversion.

* Update CHANGELOG.md
