* Merged PR 10748585: Recall | Connect UserActivity to support restoring from snapshots
## What
Thanks to @<Brendan Elliott ⌨> for his PoC !10573092
This PR is going to use `UserActivity` APIs to connect the app to Recall so that we can take a snapshot when asked and then retore our states from the snapshot later.
## How
- Add a new type `SnapshotLaunchArguments` to identify a protocol launch requested by Recall.
- Add an extension `LaunchExtensions` as helper to retrieve key information from fundamental types.
- Refactor `App::OnActivated()` and `MainPage::OnNavigatedTo()` to handle different protocols properly.
- Create or parse `UserActivity` in `MainPage` in the way like what the PoC is doing.
- Improve the coding style a bit for `MainPage`.
## Note
The serialization work and restoring from JSON is going to be done in a separate PR.
## Testing
Manually tested.
Some typical test cases:
- Launch the app from *Start menu*
- Launch the app from *Task bar*
- Launch the app from *Command line*
- Launch with the protocol for Recall
- Launch with the protocol that is injected with evil data.

* Merged PR 10741448: [Recall] Snapshot saving and restoring
####What
According to PM [Spec](https://microsoft.sharepoint-df.com/:w:/t/PAXEssentialExperiences421/EcpP5tGRtFdIsRrP84ueRfUBjb6tfayxWtF9ujvJuNx6Dg?e=AeRzVf), saving and restoring Calculator snapshot when required.
The current snapshot supports to:
- Restore the calculator mode.
- Restore the current calculation (display value and expression).
- Restore the history of calculations (either in Standard mode or Scientific mode) shown at the time the snapshot was taken.
- Restore the current calculation error state, if applicable.
####How
- Added `SnapshotHelper` to help save and restore snapshots.
- Besides the existing snapshot information from view models, added an extra field `SnapshotVersion` in `ApplicationSnapshot` for backward compatibility.
#### Note
Unit tests will be added in a separate PR.

* Merged PR 10772614: Recall | Update the LaunchURI design
## What
Since `System.Uri` already has the `Segment` property which contains the parsed path blocks, Query in Uri looks too heavy and intrusive in implementation to retrieve the activity id.
## Changes
Changed the launch URI from something like `ms-calculator:///snapshot?activityId=<a guid>` to `ms-calculator:snapshots/<a guid>`

* Merged PR 10778666: Recall | Show error dialog if launching from snapshot has failed
## What
Per Figma design, we can show an error dialog with messages for the failures happens during snapshot launch.
## Notes
- Fixed a crash about taking a snapshot when Calculator hasn't initialized a standard calculator.
- Simplified the restore path.

* Merged PR 10790341: [Recall] Update calculator engine with snapshot for further calculations
####What
When restoring from snapshot, we need to set calculator engine properly to make further calculations correct.
####How
Update calculator engine by a serial of corresponding commands from snapshot.
To get the commands for the display area when saving snapshot,
1. If the expression is not from history and the primary display is the result of the expression, `DisplayCommands` of `StandardCalculatorSnapshot` will be empty, and we will use the commands from `ExpressionDisplay` for restoring in the future.
2. If the expression is not from history and the primary display is not the result of the expression, `DisplayCommands` of `StandardCalculatorSnapshot` will be the commands from the history collector in addition to the operand command in the primary display, and it will be used for restoring in the future.
3. If the expression and primary display are from history, `DisplayCommands` will be incomplete with the operand command in the primary display missing as by current design of history, and the commands from `ExpressionDisplay` will be used for restoring in the future.

* Merged PR 10802927: Recall | Add threat model
## What
The support for Recall introduced a URI activation process allowing the Recall app to launch Calculator with desired snapshot metadata. This led to a potential security problem, and we need to address it by providing justifications.
Threat model is a well-known practice among Inbox Apps. After offline discussion, we decide to add diagrams for this Recall feature to prepare for the security review.

- The PR #1426 can cause a crash when no users are returned via `User::FindAllAsync(UserType::LocalUser)` when subsequently trying to access the first user. The existing code also does not guarantee that the returned user is the currently active user.
- This fix retrieves the user that opened the app and passes this user into a function to check if this user has the proper permissions to access the graphing mode. This makes sense since the active user is indistinguishable (at least from the app's perspective) to the user who opened the app. This user's permissions are then propagated downwards to properly set up the navigation menu of the app.
- Implementation detail worth pointing out: `s_categoryManifest` is what is used to populate the navigation menu of the app, but this variable is static by design, so a separate function was written to override the appropriate `isEnabled` value in `s_categoryManifest`. This function is called by `onLaunched`.
- Manual testing

Initial PR for the feature/GraphingCalculator feature branch, part of #338.
The feature incorporates a proprietary Microsoft-owned graphing engine to drive graphing experiences in the Windows Calculator app. Due to the private nature of the graphing engine, the source available in the public repo will make use of a mock graphing engine. See README.md for more details.
This PR simply serves as a base for future feature development. As such, the PR will be immediately merged. Feedback on the content of this PR, and on the feature in general, is encouraged. If there is feedback related to the content of this specific PR, please leave comments on the PR page. We will address the comments in future PRs to the feature branch.
