feat/fix(mobile): add translations (en-fr) and fix some UI glitch

[clementdelestre]

Hello,

Here is the content of this PR:

• I added several missing translations (throughout the application), in English and French.
• I fixed some widget overflows (often due to long text overflow)
• I fixed text breaks in the ControlBottomAppBar options for some languages
• I rounded the edges of certain dialogs so that they fit better into UI (delete_dialog and confirm_dialog).

Thanks

Can you help include the screenshot of before and after for the UI modification?
