fix!: preserve detail from upstream address parse errors - #1138

Description

Fixes #1095

AddressParseError discarded the upstream error in seven of ten arms, reporting only a generic label such as "base58 address encoding error". Every variant now carries an error_message holding the upstream detail:

Notes to the reviewers

Why the conversion follows each error's source() instead of relying on to_string() alone.
The detail sits two levels below ParseError::Base58. The wrapping errors use the write_err! macro, which leaves the source out of Display when the std feature is enabled — so to_string() returns "base58 error" and nothing else, and the rest is reachable only through source().

Scope. The issue names Base58, Bech32 and network validation. This also covers the four other arms that discard the error the same way, plus OtherAddressParseErr, which had no payload at all. The change breaks the generated bindings either way. Happy to narrow it to the three named variants if you'd prefer.
