docs: cut 6.1.0 versions for docs, admin_docs, developer_docs, components

Snapshots all four versioned Docusaurus sections at v6.1.0. Built on
top of the version-cutting tooling work in chore/docs-cut-6.1.0-versions
so the snapshot benefits from:

- Auto-gen refresh before snapshotting (database pages from engine
  spec metadata, API reference from openapi.json, component pages
  from Storybook stories) — captured at the SHA we cut from rather
  than whatever happened to be on disk.
- Data-import freeze: country list, feature flag table, database
  diagnostics, and component metadata are copied into snapshot-local
  `_versioned_data/` dirs so the historical version doesn't silently
  mutate when the source files change.
- Depth-aware import-path rewriter that handles deeply-nested
  component MDX files referencing `../../../src/` from the snapshot.

Versioning behavior: `lastVersion` stays at `current` for every
section, so the canonical URLs (`/docs/...`, `/admin-docs/...`,
`/developer-docs/...`, `/components/...`) continue to render content
from master. The `current` version is consistently labeled "Next"
with an `unreleased` banner, and `6.1.0` is a historical pin
accessible only via its explicit version segment.

Component playground: previously `disabled: true` in versions-config.json,
now enabled and versioned. The plugin block in docusaurus.config.ts
was already gated only by the `disabled` flag, so no other code
changes were needed to bring it back online.

The frozen `databases.json` in the snapshot is the canonical 80-database
artifact from the latest committed state in master (preserved by the
generator's input-hash cache), not a fallback regenerated from a
local Flask environment.

+# Map tiles
+
+Superset uses OSM and Mapbox tiles by default. OSM is free but you still need setting your MAPBOX_API_KEY if you want to use mapbox maps.
+
+## Setting map tiles
+
+Map tiles can be set with `DECKGL_BASE_MAP` in your `superset_config.py` or `superset_config_docker.py`
+For adding your own map tiles, you can use the following format.
+
+```python
+DECKGL_BASE_MAP = [
+    ['tile://https://your_personal_url/{z}/{x}/{y}.png', 'MyTile']
+]
+```
+Openstreetmap tiles url can be added without prefix.
+```python
+DECKGL_BASE_MAP = [
+    ['https://c.tile.openstreetmap.org/{z}/{x}/{y}.png', 'OpenStreetMap']
+]
+```
+
+Default values are:
+```python
+DECKGL_BASE_MAP = [
+    ['https://tile.openstreetmap.org/{z}/{x}/{y}.png', 'Streets (OSM)'],
+    ['https://tile.osm.ch/osm-swiss-style/{z}/{x}/{y}.png', 'Topography (OSM)'],
+    ['mapbox://styles/mapbox/streets-v9', 'Streets'],
+    ['mapbox://styles/mapbox/dark-v9', 'Dark'],
+    ['mapbox://styles/mapbox/light-v9', 'Light'],
+    ['mapbox://styles/mapbox/satellite-streets-v9', 'Satellite Streets'],
+    ['mapbox://styles/mapbox/satellite-v9', 'Satellite'],
+    ['mapbox://styles/mapbox/outdoors-v9', 'Outdoors'],
+]
+```
+
+It is possible to set only mapbox by removing osm tiles and other way around.
+
+:::warning
+Setting `DECKGL_BASE_MAP` overwrite default values
+:::
+
+After defining your map tiles, set them in these variables:
+- `CORS_OPTIONS`
+- `connect-src` of `TALISMAN_CONFIG` and `TALISMAN_CONFIG_DEV` variables.
+
+```python
+ENABLE_CORS = True
+CORS_OPTIONS: dict[Any, Any] = {
+    "origins": [
+        "https://tile.openstreetmap.org",
+        "https://tile.osm.ch",
+        "https://your_personal_url/{z}/{x}/{y}.png",
+    ]
+}
+
+.
+.
+
+TALISMAN_CONFIG = {
+    "content_security_policy": {
+        ...
+        "connect-src": [
+            "'self'",
+            "https://api.mapbox.com",
+            "https://events.mapbox.com",
+            "https://tile.openstreetmap.org",
+            "https://tile.osm.ch",
+            "https://your_personal_url/{z}/{x}/{y}.png",
+        ],
+        ...
+}
+```
