fix: MudBlazor v8 compatibility, static asset conflict, deploy host domain

- fix CS0542: rename Users/Assets private members to _users/_assets
- fix CS0246: MudDialogInstance -> IMudDialogInstance
- fix AppTheme: PaletteLight/PaletteDark, string[] FontFamily, string typography values
- fix DataCollectionMonitoring: @(ticker.DataPointCount)개 Korean char parsing
- fix SchedulerService: add missing Hangfire namespaces, fix GetJobStatus return type
- fix Program.cs: move PostgreSQL setup above Hangfire registration
- fix ConfirmDialog: BackdropClick, Canceled spelling for MudBlazor v8
- fix static asset conflict: remove wwwroot/_framework from git tracking
- chore: add wwwroot/_framework/ to .gitignore
- ci: change DEPLOY_HOST from IP to quant.taxbaik.com domain
