Study Period Offerings: Decimals in Funded Days [PENDING DISCUSSION]

**Describe the task**
This issue addresses the study period offerings for the institution user where decimals are displayed for the funded study period days and unfunded study period days when there are two sets of study breaks and the combined study breaks exceeds the 10% threshold

E.g. 235.6 for funded study period days and 0.4 for unfunded study period days

**Acceptance Criteria**
- [ ] Review rounding for all fields in the study period breakdown
- [ ] Review impact to students

**Additional context**

No files or tests are named. Start by tracing the study period breakdown shown to institution users, then clarify the rounding rules and review the impact on students; done means all breakdown fields follow an agreed rule and the displayed funded and unfunded days no longer show unintended decimals.
