This PR makes the multi-tool usable when zoomed in or when the browser window is narrowed a lot. (#3897)

# Description of Changes

This PR fixes responsiveness issues with the multi-tool interface when
zooming/narrowing the screen, implementing a zoom-responsive sidebar and
resolving navbar scaling conflicts.

## What was changed

• **Zoom-Responsive Sidebar**: Converts horizontal bottom buttons to
vertical left sidebar at 175%+ zoom using CSS media queries.

• **Fixed Navbar Scaling Bug**: Prevents desktop zoom from triggering 3x
mobile navbar scaling by requiring actual mobile device detection.

• **DPR Detection**: Uses Device Pixel Ratio to distinguish window
narrowing (3rem buttons) vs browser zoom (2.5rem buttons)

## Why the change was made

- **Accessibility**: Users zooming for accessibility reasons were
getting poor UX with bottom floating buttons
- **Bug Fix**: Desktop zoom was incorrectly triggering mobile navbar
scaling (3x size), making the interface unusable
- **Multi-context Support**: Different users narrow windows for
split-screen work vs zoom for accessibility - each needs different icon
sizes
