refactor(admin): split workshop, vendor-compliance, advisory-board/documentation pages

Each page.tsx was >500 LOC (610/602/596). Extracted React components to
_components/ and custom hook to _hooks/ per-route, reducing all three
page.tsx orchestrators to 107/229/120 LOC respectively. Zero behavior changes.
