feat: add configurable timeouts (#673)

## ℹ️ Description
- Related issues: #671, #658
- Introduces configurable timeout controls plus retry/backoff handling
for flaky DOM operations.

We often see timeouts which are note reproducible in certain
configurations. I suspect timeout issues based on a combination of
internet speed, browser, os, age of the computer and the weather.

This PR introduces a comprehensive config model to tweak timeouts.

## 📋 Changes Summary
- add TimeoutConfig to the main config/schema and expose timeouts in
README/docs
- wire WebScrapingMixin, extractor, update checker, and browser
diagnostics to honor the configurable timeouts and retries
- update translations/tests to cover the new behaviour and ensure
lint/mypy/pyright pipelines remain green

### ⚙️ Type of Change
- [ ] 🐞 Bug fix (non-breaking change which fixes an issue)
- [x] ✨ New feature (adds new functionality without breaking existing
usage)
- [ ] 💥 Breaking change (changes that might break existing user setups,
scripts, or configurations)

## ✅ Checklist
- [x] I have reviewed my changes to ensure they meet the project's
standards.
- [x] I have tested my changes and ensured that all tests pass (`pdm run
test`).
- [x] I have formatted the code (`pdm run format`).
- [x] I have verified that linting passes (`pdm run lint`).
- [x] I have updated documentation where necessary.
