Speed up measurement and log pages

The measurement analysis and list views could take several seconds to load on high-volume procedures, and the logs page was slow on large log histories. A round of optimizations removes those slow queries so these pages stay fast as your data grows.

• Reworked how the measurement views load data, cutting load times from seconds to milliseconds.
• Sped up the logs page on large log histories.
• Removed redundant queries by deriving sidebar filter counts from data the page already loads.
• Changes apply automatically on both cloud and self-hosted instances, with no manual setup.
