Redesigns the session detail page to match the profile page and rebuilds the session replay player.

Added

• Replay scrubber with an activity waveform from the recorded interactions, clickable page bands, grouped event markers and rage-click markers
• Replay controls: skip idle time (on by default, with a badge while skipping), playback speed 0.5×–8×, jump 10 seconds, previous/next event, fullscreen
• Replay keyboard shortcuts: Space/K play-pause, J/L ±10s, ,/. previous/next event, </> speed, I skip idle, F fullscreen
• Phone frame for recordings with a portrait viewport; the stage sizes itself to the recording
• Session page journey strip showing each page visited with time on page, entry and exit
• Session page timeline grouping events under the page they happened on, with elapsed time and property tags

Changed

• Session page header shows the visitor, date, duration, location, referrer, device, OS and browser, with "Watch replay" and "Copy id" actions
• Session metrics (duration, page views, unique pages, events, time per page, revenue) shown as a metric strip
• Session details split into Session, Source and Device tabs, next to a visitor card, groups, AI usage and popular events
• Replay activity feed lists every event, dims upcoming ones, highlights the current one and follows playback

Fixed

• Replays longer than the first batch of chunks stopped early: the timeline ended where the first batch did (e.g. 0:53 of a 1:44 recording)
• The session page showed at most 50 events; it now loads all of them (up to 2,000) and says when the list is still loading, failed or capped
• Paged event lists (events, profile, group and cohort event tables) skipped events that shared a second with the last row of a page

Summary by CodeRabbit

• New Features
  • Session details now show key metrics, page journeys with entry and exit pages, visit durations, and an event timeline with elapsed times and event details.
  • Session properties include session, source, and device details, alongside visitor and group information. Session pages offer replay and copy-ID actions.
  • Session event history loads additional results in the background and provides retry and event-limit notices when applicable.
  • Session replay includes playback speed and idle-time controls, keyboard shortcuts, event navigation, and an activity feed.
  • The replay timeline highlights page visits, activity levels, and rapid-click indicators. Selecting an event jumps to its point in the recording, and the replay frame adapts to phone or browser recordings.
