Subject: [PATCH 032/548] feat(nft): enable eth with non fungible tokens
 (#2049)

This commit introduces the functionality to enable EVM based coin as a platform coin along with its associated Non-Fungible Tokens (NFTs) owned by user. It includes enable_nft implementation, which works same way as enable_erc20.

Subject: [PATCH 265/548] feat(ETH): add `gas_limit` coins param to override
 default values (#2137)

This commit does the following:
- Increases the default consts for erc20 ops (to the old value actually) to ensure proxied erc20 would have enough gas.
- adds `gas_limit` param that can be set in coins config to allow setting lower (or higher) gas limits for selected tokens.

Subject: [PATCH 266/548] feat(nft-swap): add standalone maker contract and
 proxy support (#2100)

This commit introduces the following key changes related to issue #900:

- Implement standalone NFT maker swap contract (EtomicSwapMakerNftV2)
- Add komodefi-proxy support for NFT feature, enabling HTTP GET requests

Additional changes include:
- Implement Multi Standalone Etomic Swap contracts approach
- Add support for EtomicSwapTakerV2 contract
- Enhance security with checks for malicious token_uri links
- Make clear_all parameter optional in clear_nft_db RPC (default: false)
- Implement Sepolia testnet support for testing

This change adopts the new Etomic swap implementation approach as discussed in https://github.com/KomodoPlatform/etomic-swap/pull/7#issuecomment-2074382943

+This file is not included in the workspace. It's intended to be used to trigger the tests within docker_tests/sia_docker_tests.rs on their own 
+without running unrelated docker containers from the docker_tests_main.rs::docker_tests_runner function.
+
+An environment variable, SKIP_DOCKER_TESTS_RUNNER, can be set to skip the docker container initialization. This will run the tests with the assumption
+that there is a walletd instance at 127.0.0.1:9980. This was added to help with debugging the tests in a local environment.
+It can be useful otherwise to inspect the state of the walletd instance after the tests have run.
+
+Usage:
+    Run all sia docker tests:
+        cargo test --test docker_tests_sia_unique --all-features -- --nocapture
+
+    Run a specific test:
+        cargo test --test docker_tests_sia_unique --all-features test_sia_endpoint_debug_mine -- --nocapture
+
+    Run all sia docker tests without running the docker container:
+        SKIP_DOCKER_TESTS_RUNNER=1 cargo test --test docker_tests_sia_unique --all-features -- --nocapture
+
+    Run a specific test without running the docker container:
+        SKIP_DOCKER_TESTS_RUNNER=1 cargo test --test docker_tests_sia_unique --all-features test_sia_endpoint_debug_mine -- --nocapture
+
+note: `--nocapture` is shown in the example usage, but it is not neccesary.
