fix: submission round completion %, document details, project teams UX

- Fix 0% completion on SUBMISSION pipeline cards — now based on teams
  with uploads / total projects instead of evaluation completions
- Add page count, detected language, and non-English warning indicator
  to Recent Documents list items
- Add project avatar (logo) to document and project list rows
- Make document rows clickable into project detail page
- Remove team name from project list (none have names), show country only
- Rename "Teams Submitted" to "Teams with Uploads" for clarity
- Add "See all" link to Projects section → /observer/projects
- Rename section from "Project Teams" to "Projects"
