Treat dict log_config without a version key as an overlay on uvicorn defaults.

A partial log_config (no "version" key) is deep-merged over uvicorn's
default config before our patching, so users pass only their
customizations, e.g. log_config={"loggers": {"myapp": {"level":
"DEBUG"}}}.  Previously such dicts crashed at startup: dictConfig
requires a version, and our root entry referenced a "default" handler
that might not exist; that reference is now only added when the handler
exists.  The stock default formatter is replaced only when untouched,
so an overlaid fmt survives.  Dicts with version and non-dict configs
behave as before.  Documented in the README logging section, with tests
under fastapi-vue/tests (each patched config validated through
dictConfig).

-Logging is integrated as well: removes noisy uvicorn logging, replacing it with prettified log formatting, a colored access log and tracebacks rendered by [tracerite](https://pypi.org/project/tracerite/).

+
+### Logging and exceptions
+
+Pretty logging is configured automatically across the host process and all workers, at INFO in development and WARNING in production, with emoji level prefixes, colored access logs, and tracebacks rendered by [tracerite](https://pypi.org/project/tracerite/). With `FastAPI(debug=True)`, **Internal Server Error** responses use tracerite formatting as well.
+
+Application code can simply use `logging.info()` through `logging.exception()`, or ordinary `logging.getLogger("myapp")` loggers, without setting up logging itself. Set any logger's level when part of the application should be quieter or more verbose, for example `log_config={"loggers": {"myapp": {"level": "DEBUG"}}}`, accepting additions and overrides using [Python's logging configuration schema](https://docs.python.org/3/library/logging.config.html#logging-config-dictschema).
+
 ### Environment (fastapi_vue.env)
 
 We use environment variables to pass values between program components, from devserver script setting dev mode and telling backend and frontend URLs, to your CLI, which in turn runs the FastAPI app that may also need access to this information. The variables are prefixed by the current application name to avoid conflicts. The CLI entry point should set one like `os.environ["FASTAPI_VUE"] = "MY_APP"`, before using `server.run`
