[Phase 12] Wire conflict recovery actions into the TUI

[cosentinode]

Scope

Show active operation, unresolved count, and applicable continue/abort/rebase-skip actions in normal and compact layouts using the existing plan/preview/confirmation/audit path; update smoke documentation.

Acceptance Criteria

• Merge/rebase states and actions are prominent in both layouts.
• Conflict rows remain first and continue explains resolve/stage prerequisites.
• Uppercase Y is required for recovery actions.
• Every result refreshes state and appears in repo-aware audit history.
• TUI remains responsive and restores the terminal.

Verification

• cargo fmt --all --check
• cargo clippy --locked --workspace --all-targets -- -D warnings
• cargo test --locked --workspace
• Manual temporary-repository merge/rebase smoke
