Warn once when writing to temporary internal database

The internal database defaults to a temporary file that is deleted on shutdown. Plugin writes that expect persistence currently vanish silently. Detect such writes via an `internal_ephemeral_writes()` context manager in `datasette.database`: Datasette wraps `_refresh_schemas` (its own catalog/metadata writes) with the marker, and `Database.execute_write_fn` prints a one-time stderr warning when a write hits a `is_temp_disk` database without the marker set. The warning recommends restarting with `--internal path/to/file.db` for persistence.

-Index of the documented template contexts for Datasette's core HTML pages.

-This module deliberately contains no documentation strings of its own -
-the documentation lives next to the code it describes:
-
- Every page renders a Context dataclass defined in its view module
-  (DatabaseContext, QueryContext in views/database.py, TableContext in
-  views/table.py, RowContext in views/row.py). Fields added by view code
-  carry ``help`` metadata; fields declared with from_extra() take their
-  documentation from the description on the matching Extra class in
-  views/table_extras.py.
- The keys render_template() adds to every page are documented in
-  TEMPLATE_BASE_CONTEXT in datasette/app.py, next to the code that adds
-  them.
-
-The contract tests in tests/test_template_context.py assert that the real
-rendered context for each page exactly matches what is documented, and
-docs/template_context_doc.py generates docs/template_context.rst from the
-same classes.
