What does this PR do?

apply_patch already returns per-file diff metadata, but the CLI permission view still treated patch approvals like a single-file edit and only showed one diff block. This updates the TUI approval renderer to use metadata.files when present, keep each file path as a header, and place the whole patch set inside one shared scroll area so multi-file reviews are easier to navigate.

It also adds explicit apply_patch rendering in run mode so non-interactive CLI output prints one diff block per changed file instead of falling back to generic tool output.

How did you verify your code works?

• Ran bun run typecheck in packages/opencode
• Reproduced a multi-file apply_patch locally in TUI and confirmed all file diffs render in one scrollable view with per-file headers

The following comment was made by an LLM, it may be inaccurate:

Based on my search, I found one potentially related PR:

PR #15893: fix: re-read files after formatting in apply_patch
#15893

This PR is related to apply_patch functionality. While it focuses on re-reading files after formatting rather than rendering diffs, it addresses the same feature area and may have overlapping concerns with PR #17080's changes to apply_patch behavior.

All other search results returned PR #17080 itself or unrelated PRs.
