Automate app-base injection during FTP deploy

-- Frontend base path: set `<meta name="app-base" content="/picknplay">` in `wwwroot/index.html` for production so API calls include the subpath (keep blank for local/root).
+- Frontend base path is injected during deployment by `scripts/deploy-ftp.ps1` using deploy profile `BasePath` (falls back to last `RemoteDir` segment if omitted). This keeps local `wwwroot/index.html` unchanged while production API calls target `/picknplay/api`.
 - Deployment script: copy `scripts/deploy-ftp.profile.sample.psd1` to `scripts/deploy-ftp.profile.psd1`, fill environment values, then run `pwsh ./scripts/deploy-ftp.ps1 -ProfilePath ./scripts/deploy-ftp.profile.psd1`.
 - Shortcut command: run `pwsh ./deploy.ps1` from repo root to deploy with the local profile directly.
 - Prefer `WinScpSessionName` in the deploy profile to avoid embedding FTP credentials in scripted URLs.
