Fixes #54482
**Description**
_đź“Ś Day-of-Month (DOM) and Day-of-Week (DOW) Conflict in Cron_
In cron syntax, both Day-of-Month (DOM) and Day-of-Week (DOW) fields are
evaluated independently.
If both are specified, the schedule runs when either condition matches
(logical OR), not when both are true together.
_Example_
Cron expression : * * */1 * 5
*/1 → effectively means every day of the month
5 → every Friday
Together → Every minute (or) Every minute, only on Friday (but since */1
means every day, the Friday part becomes
redundant).
⚠️ This often causes confusion because users may expect it to mean “every
Friday only” when in reality it matches “every day”.
**Approach**
- Detect when both DOM (Day of the month) and DOW (Day of the week) are
restricted (i.e., not "*").
- Then split the expression into two variants:
- One ignoring DOW (DOM only)
- One ignoring DOM (DOW only)
Each variant is described independently, and the final description combines
them using “(or)”, which matches actual cron semantics.
