Add devcontainer-reset-db command

This command provides a fast way to reset the database in devcontainers
by recreating the mariadb container and removing its data volume. This
is much faster than downloading and importing a SQL dump from Pantheon
when you only need to reset to the original seeded state.

Useful after running e2e tests that modify the database.

+
+## Description
+
+This command is faster than `uceap refresh-content` when you only need to reset the database to its original seeded state. It works by:
+
+1. Stopping and removing the mariadb container
+2. Removing the anonymous volume that contains the modified database data
+3. Recreating the container from the image with baked-in seed data
+
+This is useful after running e2e tests that modify the database (e.g., submitting an application). The database container image has seed data pre-baked, so resetting to a clean state is much faster than downloading and importing a SQL dump from Pantheon.
+
+**Note:** This command only works in devcontainers and will not work in CI or other environments.
