**Description of problem, include YAML if issue is related to notifications:**

I am working on a custom dashboard card for the [bparasite plant sensor](https://github.com/rbaron/b-parasite), which offers users to upload a photo of their plant in the config page of the card.

I could not make that work with a prompt to directly take a camera image *in the app* it did work when i accessed HA via the chrome browser on my android though. Since this feature seems to be known to be flaky on Android, I asked Gemini to create test-cases, which you can find here: https://mofef.github.io/android_camera_test.html
They **work as intended via android chrome but not if I integrate the exact same page as an iframe into my card.** It only ever shows a file picker, not offering the camera option.

The HA app does have camera permission in case that is relevant.

Since I'm not familiar with android development i asked Gemini for a hypothesis:
Currently, the Home Assistant Android app's `WebView` implementation of `onShowFileChooser` appears to only trigger the standard file picker (`ACTION_GET_CONTENT`). On modern Android versions (14+), this often defaults to the new Photo Picker or a system file picker that **omits the Camera tile**.

This makes it impossible for a user to "Take a Photo" directly from an HTML `` element within the HA app. They are forced to background the app, open the Camera app, take a photo, return to HA, and select the file from the gallery.

Here is some more of what Gemini has to say about it, but I don't have the competence to review that sadly. Please ignore unless you are interested: **trigger warning: potential AI slop**

### Testing & Diagnosis
I have tested the following HTML5 input configurations inside the Home Assistant Android App (latest version) on Android 14/15.

| HTML Input Configuration | Result in HA App | Result in Chrome (Ref) |
| :--- | :--- | :--- |
| `` | Opens Gallery (Photo Picker). No Camera option. | Gallery (Photo Picker). |
| `` | Opens Gallery. No Camera option. | **Opens Camera directly.** |
| `` | Opens System Files. No Camera option. | **Opens System Files + Camera option.** |
| `` | Opens System Files. No Camera option. | **Opens System Files + Camera option.** |

**Conclusion:** The `WebView` seems to be lacking the specific intent logic to handle `capture` attributes or to append the `MediaStore.ACTION_IMAGE_CAPTURE` intent to the chooser dialog.

### Proposed Solution
I propose updating the `WebChromeClient.onShowFileChooser` override in the Android app to explicitly add the `ACTION_IMAGE_CAPTURE` intent to the chooser options.

This is a standard pattern for Android WebViews to support HTML5 camera inputs. By creating a `takePictureIntent` and adding it to the `Intent.createChooser` extra `EXTRA_INITIAL_INTENTS`, the `WebView` will present the user with both the File Manager and the Camera.

I'm not an Android developer (last contact point 2011) but I'm in SWE since 10 years so I'm happy to take directions and prepare a PR.
