Replace the CLI-only setup (db:seed + manual application.rb edits)
with a web wizard shown automatically on first visit when no admin
account exists yet.
SetupController (GET/POST /setup) collects the admin e-mail and
password, a "skip e-mail confirmation" toggle, and an option to
seed the built-in default units. Once submitted it creates the
admin User, persists the chosen options as Setting records, and
redirects to the sign-in page.
ApplicationController gains a redirect_to_setup_if_needed
before_action that catches every request (including Devise routes)
when no admin exists, so a fresh installation always lands on the
wizard rather than an empty sign-in form.
A new Setting model provides a lightweight key-value store for
runtime options that were previously hard-coded in application.rb
(e.g. skip_email_confirmation). RegistrationsController now reads
that flag from the database instead of from the application config.
Seeds.rb is kept for headless / automated deployments and skips
admin creation when an admin already exists (idempotent), with a
comment pointing to the web wizard as the preferred path.
Also extends the SQLite nil-limit fix (|| Float::INFINITY) to the
Quantity model, which suffered the same ArgumentError as Unit.

Introduce config.skip_email_confirmation in application.rb.dist.
When set to true, new registrations are automatically confirmed
without requiring email verification — useful for installations
where outgoing email is not configured or for development/testing.
Implemented by calling skip_confirmation! in build_resource before
the record is saved, so no confirmation email is ever sent.
Also fix ArgumentError raised in length validations when
type_for_attribute(:column).limit returns nil, which happens with
SQLite for string columns that have no explicit limit in the
migration. Guard with || Float::INFINITY so the validation is
effectively skipped when the database imposes no limit.
