this was only ever needed in tests, and having it on the actual
wiki-page model is just incurring technical debt and installing a
permanent footgun. It is removed and replaced with factories.

This also refactors the event spec to be much more declarative for
visibility tests.

This removes the DB timestamp column defaults, and manages those values
in the model domain object instead.

This adds validations that ensure that wiki pages cannot have the same
canonical slug in the same project. We cannot easily move this check to
the DB, so this is handled in logic - we check in `.find_or_create` if
either of the known slugs matches a record, and we raise errors on
conflict.

This also introduces some optimisations that eliminate unnecessary
queries.

Minor updates from review comments

Includes:

- Use Class#name instead of constant
- Wrap mutable state in an outer transaction

  The one subtle thing here is that the first query (to find the record)
  must be within the transaction, even though it does not mutate the state
  of the DB. This is because we learn important facts from that query
  (namely whether there are any conflicting canonical slugs) that could be
  invalidated outside a transaction.

- Use standard uniqueness validator

  This is more declarative than our hand-rolled implementation

- Move page construction into factory

  This requires a new trait for the wiki page factory to create pages that
  are in the wiki repo.

- Changes to some test descriptions

- Reduce DB queries in specs

we don't strictly need multiple slugs here - one will do.

- Avoid running validation if there is no project_id

- Raise error if there are no slugs at all
