Dry-run validate a market proposal before signing.

Pure validator — no chain, no DB, no signer. Returns a list of issues + per-field UTF-8 byte sizes + the estimated ALPH attached to the eventual tx. Use this from a “preview” screen so users see “your proposal looks good” (or what to fix) before being asked to sign anything.
