fix: prioritize largest video element, fix history action field in debug report

- findVideo() now scores all video elements by size + unmuted + duration
- Fixes Prime Video selecting 0x0 placeholder instead of actual player
- Fix history entries showing '?' by using h.action instead of h.event/h.type
- Update Prime Video status in TESTED_SERVICES.md to partial support
