fix: Clarify MinIO access credentials in UI

- Update CreateUserDialog labels to show 'Username (Access Key)' and 'Password (Secret Key)'
- Add helper text explaining these are MinIO credentials
- Enhanced success display to show credentials with proper MinIO terminology
- Add MinIO CLI connection examples in credential displays
- Fix confusion about where to get access key and secret key

This addresses user feedback about unclear credential terminology and aligns
with MinIO documentation where username = Access Key and password = Secret Key.

+## apply_diff
+```xml
+<apply_diff>
+  <path>File path here</path>
+  <diff>
+    <<<<<<< SEARCH
+    Original code
+    =======
+    Updated code
+    >>>>>>> REPLACE
+  </diff>
+</apply_diff>
+```
+
+### Required Parameters:
+- `path`: The file path to modify
+- `diff`: The diff block containing search and replace content
+
+### Common Errors to Avoid:
+- Incomplete diff blocks (missing SEARCH or REPLACE markers)
+- Including literal diff markers in code examples
+- Nesting diff blocks inside other diff blocks
+- Using incorrect diff marker syntax
+- Including backticks inside diff blocks when showing code examples
+
+### Best Practices:
+- Always verify the file exists before applying diffs
+- Ensure exact text matching for the search block
+- Use read_file first to confirm content before modifying
+- Keep diff blocks simple and focused on specific changes
