Enhance Time-Period Reporting: Detailed Summaries with Transaction Breakdown

[square-story]

Is your feature request related to a problem? Please describe.

Currently, when users type /today, /week, or /month, they receive basic balance summaries. However, users need more detailed insights to understand their financial activities better—they want to see:

• Comprehensive summaries with key metrics (total income, total expenses, net balance)
• Complete list of transactions for the specified period
• Transaction details including: date, time, vendor/contact name, amount, transaction intent/category
• Quick visual breakdown of cash flow

Describe the solution you'd like

Enhance the existing reporting commands to return detailed reports with:

1. Summary Section:

   • Total credits (income)
   • Total debits (expenses)
   • Net balance for the period
   • Transaction count

2. Transactions List:
   Each transaction should display:

   • Date & Time
   • Contact/Vendor Name
   • Amount (with direction indicator: ↓ for debit, ↑ for credit)
   • Intent/Category/Tags
   • Optional: Description/Notes from the original entry

3. Command Support:

   • /today entries → Today's transactions with summary
   • /yesterday entries → Yesterday's transactions with summary
   • /week entries → This week's transactions with summary
   • /month entries → This month's transactions with summary
   • Natural language variations like "Show me today's transactions" or "What happened yesterday?"

4. Output Format:

   • WhatsApp message: Concise summary with transaction count
   • PDF option: Detailed report with full transaction breakdown for record-keeping

Describe alternatives you've considered

• Keep responses as single messages with abbreviated transaction lists
• Generate only PDF reports without inline WhatsApp previews
• Create a web dashboard (outside scope, but potential future enhancement)
