[fix] issues when launching a local development server

A local development server can be launched by one of these command lines::

    $ flask --app searx.webapp run
    $ python -m searx.webapp

The different ways of starting the server should lead to the same result, which
is generally the case.  However, if the modules are reloaded after code
changes (reload option), it must be avoided that the application is initialized
twice at startup.  We have already discussed this in 2022 [1][2].

Further information on this topic can be found in [3][4][5].

To test a bash in the ./local environment was started and the follwing commands
had been executed::

    $ ./manage pyenv.cmd bash --norc --noprofile
    (py3) SEARXNG_DEBUG=1 flask --app searx.webapp run --reload
    (py3) SEARXNG_DEBUG=1 python -m searx.webapp

Since the generic parts of the docs also initialize the app to generate doc from
it, the build of the docs was also tested::

    $ make docs.clean docs.live
