GroupVerify: Verification page, overrides and public Verified tags

Shown only where GroupVerify is: staff get the Verification page once its gv_* tables are in
the database, and the public site shows "Verified" only while it's on (enabled, with a group)
and not missing from css_plugins list, which the poller reads once a minute over RCON.

- Verification page: plugin state and version, Steam group, saved member list, overrides.
- Overrides (@zio/verify, not on yourself unless Root): give, change, remove; player drawer
  shows why a player is or isn't verified.
- Root sets the group and turns it on/off: saved to gv_settings, and sent as css_gv_* when the
  plugin is loaded so it applies at once.
- gv_* times use GroupVerify's own timezone setting.
- MySQL integration test (SAW_TEST_DSN), unit tests for plugin list parsing and the show rule.

+### Verification (GroupVerify, optional)
+
+[GroupVerify](https://git.zio.sh/cs2/GroupVerify) (`plugins/GroupVerify` in the cs2 repo) verifies
+players who are in the server's Steam group or have a manual override, and other plugins give
+verified players perks. It keeps everything in SimpleAdmin's database (`gv_verified`,
+`gv_settings`), so the panel needs no setup for it:
+
+- **Staff** get a Verification page as soon as GroupVerify's tables are in the database: whether
+  it's on, the plugin's state and version, the Steam group, its saved member list, and the
+  overrides. The player drawer shows why a player is or isn't verified. With `@zio/verify` (give
+  it to the ranks that should have it in the rank editor), staff give overrides for a day up to a
+  year or with no expiry, change them and remove them. Root sets the group and turns verification
+  on and off.
+- **Everyone** sees a "Verified" tag on the scoreboard and on player pages, but only while
+  verification is on (enabled, with a group set) and GroupVerify isn't missing from the server's
+  plugin list. The public site never shows why someone is verified, or who gave an override.
+- **Whether it's loaded** comes from `css_plugins list` over RCON, read once a minute alongside
+  the live status. While the server is down it's unknown, and that doesn't hide anything.
+- **Changes**: overrides are written to `gv_verified` and GroupVerify picks them up on its next
+  reload (`db_reload_seconds`, 60 by default). Settings are written to `gv_settings` and, when
+  the plugin is loaded, also sent as its own `css_gv_group`/`css_gv_enable`/`css_gv_disable`, so
+  they apply at once.
+- **Times** in its tables are in GroupVerify's own `timezone` setting, which the panel follows.
+  Keep it the same as SimpleAdmin's `Timezone`.
+
+The panel never shows a group member list from Steam itself: "Steam group members" is the list
+GroupVerify last fetched and saved.
