feat(backend): add unified deeplink import command

Add a new unified command handler for importing all resource types
via deeplinks, replacing the legacy provider-only import command.

Changes:
- Add import_from_deeplink_unified command supporting all resource types
- Keep import_from_deeplink for backward compatibility (now marked legacy)
- Route imports based on request.resource field (provider/prompt/mcp/skill)
- Return typed ImportResult with resource-specific data

Return types:
- Provider: { type: "provider", id: string }
- Prompt: { type: "prompt", id: string }
- MCP: { type: "mcp", importedCount, importedIds, failed }
- Skill: { type: "skill", key: string }

The unified handler simplifies frontend logic by providing consistent
return types and error handling across all resource types.
