🎨 Palette: Standardize LevelFileDialog search and name inputs

[Zee2401]

Standardized the LevelFileDialog in the Editor by enhancing its search and name input fields. These changes improve accessibility through label buddy associations and accessible names, and improve interaction efficiency by adding placeholder text and clear buttons. Additionally, O3DE search styling was applied to the filter field to maintain visual consistency across the engine.

❌ Failed checks (2 warnings, 1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The PR title mentions 'LevelFileDialog' but the actual change shown is to 'ATLControlsResourceDialog.cpp' in the AudioSystem, which is unrelated to LevelFileDialog standardization.	Update the PR title to accurately reflect the changes, or ensure all changes align with the stated objective of standardizing LevelFileDialog search inputs.
Docstring Coverage	⚠️ Warning	Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Description check	❓ Inconclusive	The description references LevelFileDialog standardization, but the code summary shows only AudioSystem ATLControlsDialog changes, creating a mismatch between stated and actual changes.	Clarify whether the PR scope includes both LevelFileDialog and AudioSystem changes, or if the description needs updating to match the provided code changes.
