Skycoin: BIP44 Chain Selection and Release Build Fixes

BIP44 chain selection — the API, CLI, and web wallet GUI now support selecting different BIP44 derivation chains (external vs. internal/change addresses). This gives users more control over address generation for privacy-conscious workflows — change addresses can be generated separately from receiving addresses, matching standard Bitcoin wallet behavior (#2817).

Release build hardening — the cmd/release binary (which includes hardware wallet support via libusb/cgo) was fixed to compile correctly on platforms where cgo is available and degrade gracefully where it isn’t. The DisallowUnknownFields restriction was removed from the API client JSON decoder, which was causing failures when the API returned fields the client didn’t expect — a forward-compatibility issue that would break older clients talking to newer nodes (#2820).

Dependency updates — fast-xml-parser was bumped from 5.5.5 to 5.5.6 in the explorer to address a security advisory.
