Replaced Azure Blob Storage and Storage Queue with local
temp folders and an in-memory queue for file storage and
async processing. Updated `IFileStorage` and `IJobQueue`
interfaces to support the new architecture.
Modified `TenantSettings` and `ApplyStampHandler` to use
local file paths. Updated `JobProcessorService` to handle
in-memory queue jobs. Added file cleanup policies to
`LocalFileStorage`.
Revised roadmap and documentation to reflect the shift
to local-first architecture, emphasizing simplicity,
reduced cloud dependencies, and single-server readiness.
Logging now uses file-based storage instead of Application
Insights. Adjusted production deployment and health check
phases to align with the new approach.
