Create adapative re-categorization for transactions

[fmeiraf]

When adding multiple transactions at once editing the categories to personal taste might take too long. Try to create a second LLM call that readapts based the user input for few transactions.

One idea:

• check all the unique transaction descriptions
• Ask LLM for category
• Ask user if he accepts or wants to edit it
• Apply user choice to all transactions with same description
