feat: Refactor transaction handling and add new features

- Updated ReasonGroupList.vue to modify classify button behavior for adding new classifications.
- Refactored TransactionDetail.vue to integrate PopupContainer and enhance transaction detail display.
- Improved TransactionDetailDialog.vue with updated classify button functionality.
- Simplified BalanceView.vue by removing manual entry button.
- Enhanced PeriodicRecord.vue to update classify button interactions.
- Removed unused add transaction dialog from TransactionsRecord.vue.
- Added new API endpoints in TransactionRecordController for parsing transactions and handling offsets.
- Introduced BillForm.vue and ManualBillAdd.vue for streamlined bill entry.
- Implemented OneLineBillAdd.vue for intelligent transaction parsing.
- Created GlobalAddBill.vue for a unified bill addition interface.
