Quick Reply Attachments 1.2.5

Emergency repair build.

Fixes:
- Cleans malformed/bad hooks from 1.2.4.
- Registers exactly:
  integrate_pre_include => $sourcedir/QuickReplyAttachments.php
  integrate_display_buttons => qra125_display_buttons
- Keeps backwards alias functions safely inside the PHP source file.

Keeps:
- Working Quick Reply upload button.
- from_qr attachment fix.
- Progress percent and bar fill attempt.
- Flex rows/columns attachment cards.
- Correct file type labels/icons.
- Download/view count badge when SMF exposes that count in the original attachment markup.

No core edits. Uses integrate_display_buttons.
