AdminKit 0.1.2

AdminKit is the shared admin base for the RBN WordPress plugins. It is REQUIRED by
WPSeoKit, ContentHealth, CookieKit and SecurityKit: install and activate AdminKit first.

What is new in 0.1.2:

• System Health: a read-only report of the server, the database and WP-Cron on its own
  tabs, with a button that copies the report for support.
• Database maintenance: shows what can be cleaned (revisions, expired transients,
  orphan meta), previews the count, asks for an explicit confirmation and deletes in
  batches.
• Settings export and import: download the settings of all RBN plugins as one JSON
  file, preview what will change, then apply it in one step; the write is atomic and a
  file that fails validation changes nothing.
• Instant switches: where a screen offers them, a setting takes effect as soon as the
  switch is flipped; a change that can lock you out asks for confirmation first.
• Toast notices, and one shared toast and confirm component for every RBN plugin.
• One settings engine for every module: schema-based fields, a live preview,
  per-section error messages and a single write path. Two simultaneous saves no longer
  overwrite each other.
• Central security layer: admin actions go through one capability, nonce and origin
  gate; database access goes through one query gate.
• One shared update card on the settings screen of all five plugins.
• The plugin catalog installs SecurityKit as well (it is released in the same batch, so
  the catalog shows an Install button for it).
• The sticky save bar appears only on the visible tab and only while the form is dirty;
  inner tabs follow the browser back and forward buttons, and every screen has one
  page heading.
• Fixes: the privacy mask matches whole words only, a cache flush also removes rows of
  older cache versions, and the accent color no longer leaks into WordPress' own
  buttons and links.

The package is signed (Ed25519) and its SHA-256 digest is published next to it.

Requires WordPress 6.4+ and PHP 8.0+. (The "Requires Plugins" dependency check that
blocks activation without AdminKit exists in WordPress 6.5+.)
