fix(scheduled-ops): audit log text, run attribution, prune targets, and pagination (#234)

- Fix "Run Now" audit log showing "Created scheduled task" instead of "Triggered scheduled task" by adding wildcard-based route matching with specificity sorting
- Add triggered_by column to track whether runs were started by the scheduler or manually via Run Now
- Add configurable prune targets (containers, images, networks, volumes) with checkbox UI
- Add pagination to execution history with offset-based navigation
- Document Run Now behavior on disabled tasks and add screenshots
