Speed up measurement control links and sidebar

Opening a measurement control link that already had a measurement selected made every sidebar filter fetch its options separately, even though the data was already loaded with the page.

• Improved shared links with a measurement selection: sidebar filters now reuse the data delivered with the page instead of firing six extra requests
• Improved internal consistency: measurement control now uses the same first-load data handling as all other list pages, closing the gap that caused the recent sidebar filter bug
• Fixed an edge case where certain link parameters unnecessarily skipped the fast first load
