feat(wasm-utxo)!: restructure linting scripts for granular control

Split monolithic lint commands into individual tasks for prettier,
eslint, rustfmt, and clippy. This enables running specific linters
independently and provides better control over the linting workflow.

BREAKING CHANGE: `check-fmt` now runs prettier and rustfmt instead of
both formatters. Use `lint` for comprehensive checks including clippy.
