This patch recreates the resource presets with a non-burstable memory
allocation (request==limit) and without CPU limits. With the new presets
the difference between the larger presets became meaningless, so their
values were adjusted.
Resolves #912

## Summary by CodeRabbit
- **Chores**
- Updated resource presets across all application charts to remove CPU
limits, align memory limits with requests, and standardize memory units
for consistency.
- Adjusted CPU and memory request values for larger presets in several
applications.
- Updated chart versions for all affected applications.
- Refreshed version mappings to reflect latest commit hashes.
- Added explicit resource configuration for Redis in the dashboard
configuration.
