fix: handle paste in prview and issueview inputboxes

Bug: Pasting text into the comment, approve, assign, or label inputbox
does nothing.

Cause: Bubbletea v2 enables bracketed paste by default, delivering
pasted text as tea.PasteMsg rather than individual tea.KeyMsg events.
The Update() methods in prview and issueview only had a case for
tea.KeyMsg, so PasteMsg was silently dropped.

Fix: Add a tea.PasteMsg case in both the prview and issueview Update()
methods that forwards the message to the inputbox when it’s focused.

Fixes #811
