fix(dashboard): adds dependent filters select first value fixes

[ObservabilityTeam]

Commit message:

• adds a fix for correctly selecting first value of a dependent filter
• adds a fix for automatically selecting the correct dependent filter value on changing parent filter value
• adds dependent filters fix support for time range filter

SUMMARY

These fixes address issues with dependent filters using the "Select first filter value by default" option:

• FilterValue.tsx: Prevents child filters from requesting data before their parent values are set. The request is now delayed until all parent filter data is available, ensuring correct first value selection.

• SelectFilterPlugin: Ensures the first value is correctly updated when parent filter values change. A post-check hook verifies external data changes and selects the appropriate default.

TESTING INSTRUCTIONS

1. Create a dashboard with two filters and some charts these filters are applied to.
2. Make both filters required and "Select first filter value as default".
3. Make one of the filters dependent (child) on the other.
4. Make sure the first value of the dependent filter is not available with the first value of the other filter.
5. Load dashboard in UI.
6. First value of the dependent (child) filter is NOT chosen based on it's parent filter(s)
7. If you change the value of the parent filter(s), the first value of the child does not change which should not be the case because it should reflect changes based on it's parent(s) value.
