SQLite's Arel visitor wraps CTE branches in extra parentheses, making
the UNION ALL inside recursive CTEs invalid. Also SQLite lacks LPAD()
and CAST(... AS BINARY). Fix by using the existing pathname column for
ordering on SQLite, which already encodes the hierarchical path.

Replace MySQL-specific LPAD() with SQLite's format() for zero-padded
row numbering, and skip CAST(... AS BINARY) on SQLite where string
comparisons are already binary by default.

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.

Separate scope only provided some optimisation by reducing the count of
records :numbered and should be unnecessary in future once numbering
can be merged with ordering into one recursive query
