Server Configuration Viewer Page

Create an Angular page for viewing and editing the server configuration using the existing LsmConfig infrastructure in src/infra/config.rs.

Backend Endpoints Needed

GET    /admin/config            — Current server configuration (read-only or full)
PUT    /admin/config            — Update configuration (hot-reload where supported)
GET    /admin/config/schema     — JSON Schema describing valid config structure

UI Requirements

Configuration Display

• Categorized Sections: Core, Storage, Compaction, Replication, Security, etc.
• Card-based Layout: Each config section as a collapsible card
• Read-only View: Display current values with formatting
• Edit Mode: Toggle to enable editing of hot-reloadable values

Configuration Sections

• Core: dir_path, memtable_max_size, etc.
• Storage: block_size, block_cache_size_mb, encryption, compression
• Compaction: strategy, thresholds, max_sstables
• Replication: role, endpoints, sync_interval
• Security: auth_enabled, encryption_key_path
• Logging: log_level, log_format

Edit Mode

• Inline Editing: Editable fields for supported values
• Validation: Real-time validation against schema
• Diff View: Show what changed before saving
• Save/Revert: Save changes or revert to original
• Hot Reload Notice: Indicate which changes require restart

Configuration Profile System

• Profile Selector: Quick switch between presets (development, production, high-write, low-memory)
• Custom Profile: Save current settings as a named profile
• Profile Import/Export: Download/upload profiles as JSON

Acceptance Criteria

• All configuration sections displayed correctly
• Values are formatted appropriately (bytes, durations, etc.)
• Edit mode allows changing supported values
• Validation shows errors for invalid values
• Profile switching works
• Error states for API failures
• Responsive layout
