Resolve the feeds.html conflict by keeping the branch's XSS-safe DOM
construction of the feed-details view and re-adding dev's per-feed and
reset-all error buttons via addEventListener instead of inline onclick,
since /feeds is a nonce-CSP page where inline handlers are blocked.
Update tests/test_feed_manager_extended.py::TestPollFeedPosting to patch
the SafeUrlPolicy.validate_async path (this branch's SSRF refactor) rather
than the removed module-level validate_external_url symbol, matching the
idiom already used throughout that test file.

- Added max_posts_per_check to limit the number of items posted per check, defaulting to max_items_per_check for backward compatibility.
- Updated logic in FeedManager to process new items, ensuring that only the specified number of posts are made while examining a larger set of items.
- Enhanced emoji selection to prioritize per-item emojis from the API, falling back to heuristics based on feed names when absent.
- Introduced new truncation and substring functions for formatting messages, improving text handling in feed outputs.
- Added API endpoints to reset feed error counts globally or for individual feeds, enhancing error management capabilities in the web viewer.
- Updated the `resolve_path` function in `utils.py` to clarify behavior regarding absolute paths.
- Changed type hints in `discord_bridge_service.py` for better clarity and consistency.
- Removed unused imports and unnecessary comments in various test files to improve code cleanliness and readability.
