Add standalone SwaggerUI page and single-command install script

[robit-man]

Summary

Two developer/operator-facing additions to improve onboarding and API discoverability:

1. Standalone SwaggerUI (docs/swagger/index.html)

A self-contained HTML page that provides interactive API documentation:

• Dark theme with Fortemi branding
• Configurable server URL — connect to any Fortemi instance (local or remote)
• Live health check indicator (connected/unreachable)
• Endpoint statistics bar — shows path count, endpoint count, HTTP method breakdown, schema count, tags, and API version at a glance
• Full SwaggerUI v5 with try-it-out enabled, filtering, request duration display, and persistent authorization
• URL parameter support — ?server=https://my-instance.com for bookmarkable links
• Loads spec from /openapi.yaml which covers all 223 annotated endpoints across 18 tag groups

This complements the existing /docs endpoint (utoipa-swagger-ui) by providing a standalone page that can be served independently, used for offline reference, or customized without rebuilding the Rust binary.

2. Install Script (install.sh)

Single-command deployment for the Docker bundle:

curl -fsSL https://raw.githubusercontent.com/fortemi/fortemi/main/install.sh | bash

Features:

• Prerequisite checks — Docker, Compose v2, NVIDIA GPU + Container Toolkit
• Auto-installs Docker on Linux if missing
• GPU auto-detection with graceful CPU-only fallback
• Environment generation — creates .env with sensible defaults
• Flags: --no-gpu, --no-whisper, --no-gliner, --no-diarization, --domain, --port, --data-dir, --dry-run
• Health wait — polls /health until API is ready
• Post-install summary — shows URLs, quick-start curl examples, MCP integration snippet
• Uninstall support — --uninstall with optional data volume cleanup

Endpoint coverage verification

The OpenAPI spec (loaded by SwaggerUI) is generated at runtime by utoipa from 223 #[utoipa::path] annotations across:

• crates/matric-api/src/main.rs — 186 annotations
• crates/matric-api/src/handlers/*.rs — 37 annotations (archives, audio, chat, document_types, models, pke, provenance, vision)

All 18 OpenAPI tags are covered: Notes, Tags, Search, Jobs, OAuth, System, SKOS, Collections, Embeddings, Graph, Backup, Templates, Webhooks, Attachments, PKE, Provenance, Archives, DocumentTypes.
