fix(plugin-evm): base LiFi class inheritance

[jdubpark]

Relates to:

None

Risks

Low, simple refactoring + removal of an unused parameter (mismatching type).

Background

What does this PR do?

• Refactor the SwapAction and BridgeAction, both of which use the LiFi SDK, to inherit BaseLifiAction, which de-duplicates the constructor for the two actions.
• Remove this.config from executeRoute in Swap & Bridge actions, as the type (SDKOptions) and values of this.config do not match and are not intended to be used in executeRoute, which expects hooks via the type ExecutionOptions.
• Reorder import ordering
• Add IDE folders in .gitignore

What kind of change is this?

• Bug fix: remove unused/misused parameter (found due to strict type checking, SDKConfig =/= ExecutionOptions)
• Improvements: refactoring + gitignore

Testing

Where should a reviewer start?

Does not change the existing logic of the plugin-evm.

Detailed testing steps

None

Thanks for working on this lgtm - outside of resolving merge conflicts and adding a screengrab or any confirmation that this does not introduce regressions

While the refactor is nice I don't think we want to always utilize LiFi, as these are the potential downsides:

• Tight Coupling to LiFi SDK
• Reduced Readability
• Technical Debt from Future SDK Changes
