Add visual polish and styling to frontend/app.tsx using Tailwind CSS with a background color of #FCFBFE for the main page. Style all interactive buttons and CTAs with background #6358F0 and white text, with hover:opacity-90 for the hover state. Keep the review type badges with different colors: bg-blue-100 text-blue-800 for shareout, bg-green-100 text-green-800 for brainstorm, bg-orange-100 text-orange-800 for system_feedback, and bg-purple-100 text-purple-800 for ux_ui_feedback. Style available slots with a light border and hover:border-[#6358F0] effect. Add a slot counter showing "X of Y slots available" for each session. Make the active session tab use border-[#6358F0] to match the brand color. Ensure the modal has a semi-transparent backdrop and the submit button uses the #6358F0 color.

Redesign the frontend/app.tsx interface to better support the goal of making slot booking quick and visible. Replace the date picker with a view that shows up to 2 weeks of upcoming review sessions at once, with each date as a collapsible section (default to current week expanded, next week collapsed). Add a date range selector at the top if users need to look further ahead.

Update the session tabs to show the actual pod names instead of "Session 1" etc: "AX/Workflows/Insights/AI" for session 1, "Search/Activation/Tel/Bots" for session 2, "CPX/DS/DP/Integrations" for session 3, and "Global (All Pods)" for session 4.

Implement automatic timezone conversion so all times display in the user's local timezone using Intl.DateTimeFormat().resolvedOptions().timeZone. Format all times in 12-hour format with AM/PM (e.g., "2:30 PM" not "14:30"). For each session, show both the original scheduled time and the local time if different (e.g., "2:30 PM Paris (8:30 AM your time)").

Structure each date section to show the day and date prominently (e.g., "Tuesday, March 5"), then display the time slots in a clear grid below. This gives designers immediate visibility into what's available across multiple weeks without clicking around, addressing the core pain point of the Google Doc where people had to hunt for open slots.
