[configuration] Move config sections into categories

[Montekkundan]

Brief summary of changes

• Adds a ConfigCategories table for configuration section metadata.
• Adds ConfigSettings.CategoryID and migrates existing parentless section rows out of ConfigSettings.
• Updates the configuration page, config lookup, raisinbread seeds, and config import/path helpers to use categories without changing stored setting values.

Testing instructions

• Apply SQL/New_patches/2026-05-31_config-categories.sql to a local database.
• Open http://localhost:8080/configuration/ and confirm the Configuration page loads without warnings.
• Click category tabs such as Study, Paths, Email, and Log Settings and confirm the expected settings still render.
• Confirm ConfigCategories has the moved categories and ConfigSettings no longer has rows where Parent IS NULL AND DataType IS NULL.
