feat: Introduce DocumentSelectedCard and refactor DocumentFileSelector for improved display of selected documents, and update upload success navigation.

@@ -46,12 +46,25 @@ The workflow follows a 4-step lifecycle:
 #### UI — `DocumentUploadPage`
 - Accepts `StaffDocument document` and optional `String? initialUrl` as route arguments
 - PDF file picker via `FilePickerService.pickFile(allowedExtensions: ['pdf'])`
-- File selector card: shows file name when selected or a prompt icon when empty
+- **File selector card**: displays the file name with a document icon when selected, otherwise a prompt to upload. 
+- *Note:* PDF preview/opening functionality is explicitly omitted to maintain a clean, minimal upload flow without relying on external native viewers.
 - Attestation checkbox must be checked before the submit button is enabled
 - Loading state: shows `CircularProgressIndicator` while uploading (replaces button — mirrors attire pattern)
-- On success: shows `UiSnackbar` and calls `Modular.to.pop(updatedDocument)` to return data to caller
+- On success: shows `UiSnackbar` and calls `Modular.to.toDocuments()` to return to the list
 - On failure: shows `UiSnackbar` with error message; stays on page for retry
 
+#### UI Guidelines (For Documents & Certificates)
+To ensure a consistent experience across all compliance uploads (documents, certificates), adhere to the following UI patterns:
+1. **Header & Instructions:** Use `UiAppBar` with the item name as the title and description as the subtitle. Provide clear instructions at the top of the body (`UiTypography.body1m.textPrimary`).
+2. **File Selection Card:** 
+   - When empty: Show a neutral/primary bordered card inviting the user to pick a file.
+   - When selected: Show an elegant card with `UiColors.bgPopup`, rounded corners (`UiConstants.radiusLg`), bordered by `UiColors.primary`.
+   - The selected card must contain an identifying icon, the truncated file name, and an explicit inline action (e.g., "Replace" or "Upload") using `UiTypography.body3m.textSecondary`.
+   - **Do not** embed native PDF viewers or link out to external readers.
+3. **Bottom Footer / Attestation:**
+   - Fix the attestation checkbox and the submit button to the bottom using `bottomNavigationBar` wrapped in a `SafeArea` and `Padding`.
+   - The submit button state must be tightly coupled to both the file presence and the attestation state.
+
 #### Module Wiring — `StaffDocumentsModule`
 - `UploadDocumentUseCase` bound as lazy singleton
 - `DocumentUploadCubit` bound (non-singleton, per-use)
