fix(e2e): correct E2E test constants and date logic for issue listing

- Rename TEN_DAYS to ISO_DATE_LENGTH (10) for clarity
- Add ONE_DAY constant for yesterday date calculation
- Fix end date test to use yesterday instead of a future date
- Fix table size option from '25' (non-existent) to '20'
- Remove unused startValue variable in end-date test

Closes #1784
