feat(abstract-utxo): move coin implementations from sdk modules

Move UTXO coin implementations from coin-specific modules into the
abstract-utxo module. Each coin implementation now resides in its own
directory under src/impl/ and is re-exported from the main module.

This allows coin-specific modules to simply re-export the implementations
from abstract-utxo, which simplifies maintenance and keeps the code DRY.

Migrates test files from individual UTXO coin modules into the abstract-utxo
module under test/impl/<coin>. This consolidates all tests in one place for
better organization and reuse.

Added sdk-test and mocha as devDependencies to abstract-utxo package.json.
