Add budget progress gauge inside mobile category buttons

Each depense/epargne category button on the mobile quick-entry form
now shows a fill bar plus percentage of its monthly budget already
tracked, so the user sees at a glance which categories are close to
their limit while picking one. Categories without a budget defined
in Plan show no gauge (avoids a misleading 0%). Capped at 100% —
overspend detail already lives on the dashboard's "Manque" column.

3 new Pest tests for the percentage calculation (normal, capped,
no-budget cases). 61/61 tests pass, Pint clean, verified on mobile
against production data.
