## **Description**

<!-- mms-check: type=text required=true -->

On Android, **Download State Logs** was sharing only a file path string
instead of a downloadable `.json` file. Support reproduced this on 8.2.0
(build 6019, Pixel 9a, Android 16) — tracked in
[MCWP-718](https://consensyssoftware.atlassian.net/browse/MCWP-718).

**Root cause:** `downloadStateLogs` passed a plain filesystem path to
`react-native-share`. On Android, the library only treats `file://` or
`content://` URLs as file attachments; plain paths are shared via
`Intent.EXTRA_TEXT` as text. This matches the "path string only" symptom
reported in support.

**Fix:**
1. Share state logs with a `file://` URI (same pattern already used in
Experimental Settings).
2. Add `<files-path>` to `filepaths.xml` so FileProvider can expose
files written to `RNFS.DocumentDirectoryPath`.

Unit tests updated to assert the new share URL format.

## **Changelog**

<!-- mms-check: type=changelog required=true blocking=true -->

CHANGELOG entry: Fixed an issue where Download State Logs on Android
shared only a file path string instead of a downloadable JSON file.

## **Manual testing steps**

<!-- mms-check: type=manual-testing required=true -->

```gherkin
Feature: Download State Logs on Android

  Scenario: user downloads state logs and can save the JSON file
    Given I am on an Android device with MetaMask installed and unlocked
    And I navigate to Settings → Advanced

    When I tap "Download State Logs"
    And I choose a save target (e.g. Save to Files, Google Drive, or Gmail attachment)
    Then the share sheet offers file-save targets (not just messaging apps)
    And the shared content is a valid .json file attachment
    And the file is not a plain filesystem path string
```

**Tested on:**
Physical Android device — verified on a dev build; share sheet offers
save targets and produces a valid `.json` file attachment (no path
string)

## **Screenshots/Recordings**

<!-- mms-check: type=screenshot required=true -->

N/A — fix verified manually on a physical Android device. Before
