#221 rework: derive attachment line count from blob, non-image text attachments show real lines

- image pastes scale to fit the viewer box (max-width/max-height, object-fit)
- no text/code box rendered below the image for image pastes
- link pill positioning cleaned up on the image view
- /raw for attachment pastes redirects to the file itself
- view details size now uses the attachment blob size, not empty text len

 ## Features
 
-- Text pastes and cans (multiple items in one share)
+- Multiple files in one paste
-- File attachments (one file per paste, up to 25 MB)
 - Password protected pastes
-- Expire after a specified time
+- Expir after a specified time
 - Burn after a number of views
 - Custom URLs
 - Syntax highlighting with language auto-detection (go-enry)
-- Public paste listing with search, sort and pagination
+- Local cookie based submission history
-- Cookie based saved pastes and settings
+- Cookie based settings
-- Five base themes (midnight, smooth, pastel-lavender, pastel-peach, pastel-cloud), each with a dark and light variant
+- Themes!
-- Dark mode toggle in the topbar and settings, with a configurable default
-- Polished code viewer: line-number gutter sized to the widest number and pinned during horizontal scroll, optional line wrap, jump-to-top/bottom buttons, and theme-aware scrollbars
