feat: Add PathViewer and RiskDriftCard components with templates and styles

- Implemented PathViewerComponent for visualizing reachability call paths.
- Added RiskDriftCardComponent to display reachability drift results.
- Created corresponding HTML templates and SCSS styles for both components.
- Introduced test fixtures for reachability analysis in JSON format.
- Enhanced user interaction with collapsible and expandable features in PathViewer.
- Included risk trend visualization and summary metrics in RiskDriftCard.

# Drift CLI Reference
**Sprint:** SPRINT_3600_0004_0001
**Task:** UI-024 - Update CLI documentation for drift commands
## Overview
The Drift CLI provides commands for detecting and analyzing reachability drift between scan results. Reachability drift occurs when the call paths to vulnerable code change between builds, potentially altering the risk profile of an application.
## Commands
### stellaops drift
Parent command for reachability drift operations.
```bash
stellaops drift <SUBCOMMAND> [OPTIONS]
```
---
### stellaops drift compare
Compare reachability between two scans or graph snapshots.
```bash
stellaops drift compare [OPTIONS]
```
#### Required Options
| Option | Alias | Description |
|--------|-------|-------------|
| `--base <ID>` | `-b` | Base scan/graph ID or commit SHA for comparison |
#### Optional Options
| Option | Alias | Description | Default |
|--------|-------|-------------|---------|
| `--head <ID>` | `-h` | Head scan/graph ID or commit SHA | latest |
| `--image <REF>` | `-i` | Container image reference (digest or tag) | - |
| `--repo <REPO>` | `-r` | Repository reference (owner/repo) | - |
| `--output <FMT>` | `-o` | Output format: `table`, `json`, `sarif` | `table` |
| `--min-severity <SEV>` | | Minimum severity: `critical`, `high`, `medium`, `low`, `info` | `medium` |
| `--only-increases` | | Only show sinks with increased reachability | `false` |
| `--verbose` | | Enable verbose output | `false` |
#### Examples
##### Compare by scan IDs
```bash
stellaops drift compare --base abc123 --head def456
```
##### Compare by commit SHAs
```bash
stellaops drift compare --base HEAD~1 --head HEAD --repo myorg/myapp
```
##### Filter to risk increases only
```bash
stellaops drift compare --base abc123 --only-increases --min-severity high
```
##### Output as JSON
```bash
stellaops drift compare --base abc123 --output json > drift.json
```
##### Output as SARIF for CI integration
```bash
stellaops drift compare --base abc123 --output sarif > drift.sarif
```
---
### stellaops drift show
Display details of a previously computed drift result.
```bash
stellaops drift show [OPTIONS]
```
#### Required Options
| Option | Description |
|--------|-------------|
| `--id <ID>` | Drift result ID to display |
#### Optional Options
| Option | Alias | Description | Default |
|--------|-------|-------------|---------|
| `--output <FMT>` | `-o` | Output format: `table`, `json`, `sarif` | `table` |
| `--expand-paths` | | Show full call paths instead of compressed view | `false` |
| `--verbose` | | Enable verbose output | `false` |
#### Examples
##### Show drift result
```bash
stellaops drift show --id drift-abc123
```
##### Show with expanded paths
```bash
stellaops drift show --id drift-abc123 --expand-paths
```
