Fix: Simplify diagnostic logging to resolve compilation errors

This commit simplifies or removes detailed diagnostic logging that was causing compilation errors, particularly in ScreenCaptureService.kt and potentially PhotoReasoningViewModel.kt. The primary goal is to achieve a clean build to allow testing of the underlying fixes for history context preservation and TransactionTooLargeException.

Changes:
1.  **ScreenCaptureService.kt:**
    *   I removed complex loops (`filterIsInstance<...>.forEach`) that were logging detailed properties of each Part in an AI response. These were causing "Unresolved reference: parts" and lambda ambiguity errors.
    *   I retained simpler logging for the total number of parts in an AI response and an attempt to log a summary of part types using `joinToString`, now wrapped in a try-catch for resilience.

2.  **PhotoReasoningViewModel.kt (Manual Intervention Requested):**
    *   Previous attempts to add detailed logging for `content.parts` within `rebuildChatHistory()` and `sendMessageWithRetry()` using `joinToString` with a complex `when` statement resulted in "Only one lambda expression is allowed outside a parenthesized argument list" errors.
    *   My automated attempts to remove or fix these specific logging blocks have been unreliable.
    *   **If these errors persist, you should manually remove or comment out the `forEachIndexed` loops that contain the problematic `content.parts.joinToString { part -> when(part)... }` logic in `PhotoReasoningViewModel.kt` (around lines 386 and 722 of previous versions).**
    *   Simpler logs (e.g., history list sizes) and Bitmap property logging remain.

This prioritizes a compilable state. The comprehensive DTO/mapper changes to fix history context are included. After this, the main focus will be on user testing to confirm if the "history size: 2" issue is resolved.
