Attach images pasted into the composer, comments and chat

Browse Source 
Pressing Ctrl+V with a screenshot on the clipboard now attaches it
immediately instead of requiring a trip through the file picker.

The clipboard reader lives in dp-upload behind a new opt-in `paste`
boolean attribute: with it set, the component binds one paste listener
on its closest form and routes the clipboard image files through the
same handleFiles path as the picker and the drop target, so validation,
limits, the terms gate and the hidden attachment_uids field are shared.
A paste carrying plain text is never swallowed.

It is opt-in rather than a form-wide default because a form may hold
several upload buttons - projects.html has cover and logo beside the
attachment one - and a default would attach one pasted screenshot to
all of them.

Set on _attachment_form.html, so every form including it inherits the
behaviour (post composer, post edit, gists, projects, issues,
screenshots), plus _comment_form.html, messages.html and the embed-mode
skeleton AppChat builds.

**Paste-to-attach is the opt-in `paste` boolean attribute**, not a per-form handler. With it set, `dp-upload` binds ONE `paste` listener on its `closest("form")` and routes the clipboard's image files through the same `handleFiles` path as the picker and the drop target, so validation, limits, the terms gate and the hidden `attachment_uids` field are shared - never re-implement a clipboard reader in a page controller. It is opt-in because a form may hold several upload buttons (`projects.html` has cover + logo beside the attachment one) and a form-wide default would attach one pasted image to all of them; mark exactly the button that owns the form's content attachments. Set on `_attachment_form.html` (so every form including it - post composer, post edit, gists, projects, issues, screenshots - inherits it), `_comment_form.html`, `messages.html`, and the `mode="embed"` skeleton `AppChat` builds. Non-image clipboard payloads fall through untouched, so pasting text still types.
The component validates size/type/count and reports errors via `app.toast`. CSS is `.dp-upload-*` in `components.css`; the old `.attachment-upload-*` upload-widget styles were removed, but the `.attachment-gallery`/`.attachment-lightbox` display styles (for already-saved attachments) remain.
