Fix somes invalid imports introduced in the previous commits.
Also support numpy v1 and v2 with a fallback import.

This probably changed with some python upgrade.

Since numpy 1.18 creating ragged arrays requires explit opt-in via
dtype-object [1].

Let's to that then.

[1]: numpy/numpy#14794

ic_electrodes was renamed to icephys_electrodes and the same for
add_ic_electrode/create_ic_electrode.

Since pynwb 1.1.0 the unit for stimuli are hardcoded, but supplying a
different one gives a warning. So let's just pass in the correct one.

[1]: NeurodataWithoutBorders/pynwb#1186 (comment)

The SweepTable was the first icephys table for grouping different patch
clamp series together, see NeurodataWithoutBorders/pynwb@21f91920 (Add a
SweepTable for icephys data, 2018-11-02) for pynwb 0.6.0.

This was superseeded by the icephys metadata tables introduced in pynwb
2.0.0 and finally removed in 3.0.0.

While migrating to the icephys metadata tables is on the list [1], we
don't want to do this here now.

So let's add a nasty hack for injecting a sweep table.

…bility

This is removed in python 3.12. And we can also directly use __version__.

… module

This is removed in python 3.12.

We can leverage the importlib.resources module introduced in python 3.9
instead.

…ackage

This is required for the python 3.14 CI job as not all packages ship
wheels.

This is required for the python 3.14-rc on premise job as not all packages
ship wheels.

The on-premise tests were fixed in 078bda8 (Merge pull request #581 from
AllenInstitute/fix-on-premise-tests, 2025-08-26) and also passed on
master [1]. Now they are not passing again with an error like:

credentials = dict((k, os.environ.get(env_var, LIMS_DB_CREDENTIAL_DEFAULTS[env_var]))
        for k, env_var in LIMS_DB_CREDENTIAL_MAP.items())
KeyError: 'LIMS_PASSWORD'

The dict LIMS_DB_CREDENTIAL_DEFAULTS does not contain an entry with
"LIMS_PASSWORD" as key which should be okay as we are always having that
in the envrionment. But this seems to be racy as sometimes we try indexing
LIMS_DB_CREDENTIAL_DEFAULTS with "LIMS_PASSWORD" anyway.

Let's fix that by adding an entry do LIMS_DB_CREDENTIAL_DEFAULTS.

We don't have feature/XXX branches and this makes it fail.
