v2.16.0

• Set the muted text colour to #828196 and raise all 10px font sizes to 12px for readability
• Add a grouped, budget-aware category picker showing each category's available amount to the add and edit transaction modals, replacing the plain dropdown
• Show the AI-guessed category in the add-expense modal so a wrong guess can be corrected before saving
• Let an expense be added to any account, with the linked account preselected
• Put the amount and date fields side by side and align the add and edit modals
• Make the uncovered box switch to the overspent filter on click, while the Cover button still opens its menu
• Base a filtered budget group header's totals on the rows actually shown, so it no longer displays a misleading available amount
• Show a pointer cursor on the available pills
