fix(frontend): fix new session textarea overflow in Firefox

[Gkrumbach07]

Summary

• Adds overflow-y: auto to the new session textarea to prevent text from visually overflowing into the bottom toolbar in Firefox
• Firefox versions lacking field-sizing: content support keep the textarea at fixed min-h-[100px], leaving only ~52px of usable space after the pb-12 toolbar padding — long text overflows instead of scrolling

Test plan

• Open the new session view in Firefox
• Type or paste long multi-line text into the textarea
• Verify text scrolls within the textarea instead of overflowing into the toolbar
• Verify Chrome/Safari behavior is unchanged (textarea still auto-grows)
