fix(db): remove inline comments from migration 006 SQL

Migration 006 was failing during database initialization because the SQLite
plugin splits SQL statements on semicolons, and inline comments after
semicolons were being treated as separate statements. When the last statement
was comment-only (e.g., '-- Notification body text'), it caused an error.

Fixed by removing all inline comments from the migration SQL. The comments
are already documented in the TypeScript code, so they're not needed in the
SQL itself.

NOTE: We're experiencing database initialization problems with storing
notification schedule data. The daily notification plugin was originally
designed to store the schedule internally, which would be a better approach
than storing it in our SQLite database. We should consider migrating to
using the plugin's internal storage instead of adding these columns to the
settings table.
