Add observer project detail page with files, evaluations & reviews

New page at /observer/projects/[projectId] showing project info,
documents grouped by round requirements, and jury evaluations with
click-through to full review details. Dashboard table rows now link
to project detail. Also cleans up redundant programName prefixes
and fixes chart edge cases.
