Fix white filament color swatches invisible in light theme (#726)

  Changed filament color circle borders from border-white/20 to
  border-black/20 across all views so white spools are distinguishable
  against light backgrounds.

 - **Per-User Email Notifications** ([#693](https://github.com/maziggy/bambuddy/pull/693)) — When Advanced Authentication is enabled, individual users can now receive email notifications for their own print jobs. A new "Notifications" page lets each user toggle notifications for print start, complete, failed, and stopped events. Only prints submitted by that user trigger their email — other users' prints are not affected. Requires SMTP to be configured and the "User Notifications" toggle enabled in Settings → Notifications. Administrators and Operators have access by default; Viewers do not. Contributed by @cadtoolbox.
 
 ### Fixed
+- **White Filament Color Swatches Invisible in Light Theme** ([#726](https://github.com/maziggy/bambuddy/issues/726)) — Filament color circles used a white border that was invisible against light theme backgrounds, making white spools indistinguishable. Changed to a dark border (`border-black/20`) across all views: Inventory, Archives, Assign Spool, Configure AMS Slot, Calendar, Projects, Filament Trends, Local Profiles, Link Spool, and Spoolman Settings. Reported by user.
 - **Webhook Notifications Missing Camera Snapshot** ([#679](https://github.com/maziggy/bambuddy/issues/679)) — Webhook notification providers did not include camera snapshots (e.g. from First Layer Complete notifications), even though providers like Telegram, Pushover, ntfy, and Discord already attached them. The webhook payload now includes a base64-encoded `image` field when a snapshot is available (generic format only, not Slack format). Reported by @Arn0uDz.
 - **Mobile Sidebar Not Scrollable** — On mobile devices with many navigation items, the sidebar did not scroll, making bottom items unreachable. Added overflow scrolling to the nav section while keeping the logo and footer pinned.
 - **User Notification Ruff/Lint Fixes** ([#693](https://github.com/maziggy/bambuddy/pull/693)) — Fixed missing `timezone` import in email timestamp, unused lambda argument, PEP 8 blank line spacing for `mark_printer_stopped_by_user`, and SQLAlchemy forward reference in `UserEmailPreference` model.
