Add request-aware BRC-100 typed dispatch

[rohenaz]

Summary

• add typed request/result dispatch for all 28 BRC-100 WalletInterface methods
• preserve authenticated request/origin context and raw/effective permission metadata
• align failed action status and BRC-69/72/94/97 linkage behavior with the live specification and TypeScript vectors
• keep bounded/redacted wire error behavior and cancellation propagation

Verification

• BSVWalletTests: 144 passed
• BSVConformanceTests: 147 passed
• branch-wide prior run: 799 passed
• git diff --check
• independent adversarial security/behavior review: merge recommended

Downstream note

Adding the normative .failed action status requires the mobile wallet to update its exhaustive diagnosis/history switches before advancing its SDK dependency. That compatibility patch is being handled separately.

The unrelated untracked WalletBRC100JSONCodec.swift worktree file is not included in this PR.
