* fix(mobile): list Source Control changes with desktop's sections, sort and row rules
Conflicts get their own section in the user's group order, submodule rows lose stage and
discard like desktop, paths sort with the shared collator, and review notes go out as desktop formats them.
* fix(mobile): read the group order the host now publishes and keep submodule rows read-only
The host's paired settings projection now carries sourceControlGroupOrder, the
normalized status projection keeps submodule metadata, and conflict rows reuse the
shared conflict-kind labels.
* refactor(mobile): share Source Control grouping and row rules with desktop
Desktop and mobile group rows through one shared helper, mobile's unstage button
follows desktop's rule, and the group order resets when the host changes.
