What this PR does

Before this PR:

• Provider name input was trimmed on every keystroke during typing
• Users couldn't type spaces between words without them being immediately removed
• Button disabled state checked raw name length

After this PR:

• Provider name input preserves spaces during typing
• Name is trimmed only when submitting (both onOk and onClose)
• Button disabled state correctly checks trimmed name length
• Improved UX while maintaining data integrity

Why we need it and why it was done in this way

This improves the user experience by allowing natural typing behavior. Users can now type spaces between words (e.g., "My Provider") without the spaces being immediately stripped.

The following tradeoffs were made:

• Trade-off: Users can now see leading/trailing spaces in the input field during typing, but this is acceptable as the final value is properly trimmed on submission

The following alternatives were considered:

• Trimming only leading/trailing spaces on input: This would be more complex and still interfere with natural typing
• Not trimming at all: This would allow invalid provider names with whitespace

Breaking changes

None. This is a pure UX improvement with no API or data model changes.

Special notes for your reviewer

• The change ensures both onOk (submit) and onClose paths trim the name
• The buttonDisabled logic now correctly checks if the trimmed name is empty
• No changes to data models or IndexedDB schema
