When a paste is created with burn_after_read enabled, redirect to the
paste view was consuming the burn before the recipient could open it.
Fix: after creating a burn paste, the creator never navigates to the
view page. Instead, paste_create.js swaps the editor for a centered
'Burn link ready' share panel showing the full URL (with key fragment)
pre-selected in a monospace input and a Copy button. The editor and nav
controls are hidden. A 'Create another' link returns to a fresh editor.
The first person to actually open the URL is always the intended
recipient, who triggers the burn as designed.
