Fix/minfee

[2xburnt]

This pull request introduces several improvements and fixes across integration tests, coverage reporting scripts, dependency management, and core logic. The most significant changes include enhanced integration test coverage for message encoding bugs, stricter global fee bypass gas limit enforcement, and updates to coverage reporting thresholds. Additionally, there are dependency cleanups and additions for better test reliability.

Integration test improvements:

• Added TestMsgSetPlatformMinimumCodecBug to integration_tests/minimum_fee_test.go to verify that MsgSetPlatformMinimum correctly implements all required methods and encodes/decodes as expected, addressing a prior security report. (Fcdfb898L742R742)
• Improved TestWebAuthNAbstractAccount in integration_tests/webauthn_test.go by ensuring block commitment before transactions and using deterministic assertions for balance checks. [1] [2]

Global fee logic and tests:

• Added new test cases to TestGlobalFeeSetAnteHandler in x/globalfee/ante/antetest/fee_test.go to enforce and validate the maximum bypass gas limit, ensuring excessive gas usage fails as expected and boundary cases pass.

Coverage reporting enhancements:

• Updated scripts/test-coverage.sh to raise the threshold for "OK" coverage to 80%, merge low and zero coverage reporting (now <=80%), and clarify output messages for coverage validation. [1] [2] [3] [4]

Dependency management:

• Removed unused indirect dependencies from go.mod and added/testing new ones in integration_tests/go.mod for improved reliability and compatibility. [1] [2] [3] [4] [5] [6]

Minor codebase cleanups:

• Removed obsolete comments and improved import statements for clarity and correctness in various files. [1] [2] [3] [4]
