fix(frontend): prevent datetime inputs overflow in Reports Search page

[srijan2607]

Description

Fix UI overflow issue in the Reports Search page where the "End time" and "Errors" columns were overlapping/overflowing due to wide datetime-local inputs. Related issue #3096

Changes

• Added flex-wrap class to the second row to allow proper wrapping on smaller screens
• Added overflow-hidden class to Start time and End time columns
• Added maxWidth: 200px inline style to all datetime inputs to constrain their width
• Added consistent bg-darker border-dark styling to datetime inputs to match other form inputs

Type of change

• Bug fix (non-breaking change which fixes an issue).
