Add new components, typography, badge contrast, and screen layout refactors

New element components:
- ListToggle: expand/collapse button using react-icons (RiExpandVerticalLine/RiCollapseVerticalLine)
- LogLevelBadge: extracted from LogEntry, handles all 8 log levels with filled variant and dark/light text contrast

New group components:
- ViewHeader: shared header bar for ConnectedView and UnconnectedView with discriminated union on `connected` prop; MCP logo links to modelcontextprotocol.io
- ServerListControls: combines ListToggle and AddServerMenu, hides toggle when no servers
- LogStreamPanel: extracted from LoggingScreen with scroll containment, filtering by visible levels and search text
- HistoryControls: vertical sidebar with search, method filter, export, and clear
- HistoryListPanel: extracted from HistoryScreen with ListToggle compact mode, filtering by method and search text

Badge contrast improvements:
- AnnotationBadge: filled variant for both dark/light modes; black text in dark, white text in light
- LogLevelBadge: same contrast approach; bold weight for alert/emergency levels
- Badge theme default weight reduced from 700 to 600

Typography:
- Added Fredoka (300-700) as body and heading font
- Added Roboto Mono as monospace font
- Google Fonts loaded in index.html and Storybook previewHead
- Heading weight set to 600

Screen layout refactors:
- LoggingScreen: owns filterText and visibleLevels state; passes to LogControls and LogStreamPanel; removed controls prop in favor of flat props
- HistoryScreen: owns searchText and methodFilter state; passes to HistoryControls and HistoryListPanel for filtering
- Both screens use new ScreenLayout (Flex variant="screen") and Sidebar subcomponents
- Added Flex theme with "screen" variant (overflow: hidden)
- Added Paper theme "panel" variant (flex column, overflow hidden)

Component enhancements:
- ServerCard: added compact prop showing only header row
- HistoryEntry: renamed isExpanded to isListExpanded; internal useState syncs via useEffect; individual entries toggle independently
- LogControls: Select All / Deselect All toggle for level checkboxes; nowrap on level selector group
- ConnectionToggle: LoadingOverlay with rounded corners for connecting state
- ConnectedView: ThemeToggle ActionIcon matched to DisconnectButton height (36px) and border color (outline variant)
- Storybook preview: fullscreen layout wrapper with 100vh overflow hidden

New stories:
- UnconnectedView: Connecting and ManyServers (12 servers for scroll testing)
- ServerCard: CompactConnected and CompactDisconnected
- All new components have corresponding stories
