**Context:**

We weren't actually validating that the `device_vjp=True` was supported.
This allowed strange circumstances where you would have
`device_vjp=True`, but not support device derivatives at all, and this
could lead to incorrect answers.

**Description of the Change:**

**Benefits:**

**Possible Drawbacks:**

**Related GitHub Issues:**
**Context:**

When running tests locally, I was getting failures like:
```
FAILED tests/devices/default_qubit/test_default_qubit.py::TestPostselection::test_postselection_invalid_finite_shots[shots1-mp2-expected_shape2-False-jax] - ValueError: Probabilities contain NaN
```

We had logic to catch the error `'probabilities contain NaN'`, but
something about my versioning gives a slightly different capitalization.
To prevent this happening of other people, I updated the error catching
to be capitalization independent.

**Description of the Change:**

Catch both `"Probabilities contain NaN"` and `"probabilities contain
NaN"`.

**Benefits:**

Tests pass locally for my environment.

**Possible Drawbacks:**

Still a bit error prone. I'm also not sure what about my environment
gives different capitalization.

**Context:**

PR #6019 only fixes `BasisRotation` when using backprop on
`default.qubit`. It is not jit compatible on any other device. This is
because `unitary_matrix` was being considered a hyperparameter, not a
piece of data. So we could not detect that the matrix was a tracer and
we were in jitting mode, and we could not convert the matrix back into
numpy data.

**Description of the Change:**

Make `unitary_matrix` a piece of data instead of a hyperparameter. This
allows us to detect when it is being jitted.

As a by-product, I also made it valid pytree.

By making `unitary_matrix` a piece of data, we were able to get rid of
the custom comparison method in `qml.equal`.

**Benefits:**

**Possible Drawbacks:**

**Related GitHub Issues:**

[sc-51603] Fixes #6004
**Context:**

Source-code improvements found during the v0.40 quality assurance
process.

Documentation focused improvements are addressed in #6774.

**Description of the Change:**

A few things were adjusted in this PR,

**Bosonic Operators**

- `BoseX` and `FermiX` are now both top-level (as suggested by product).
- `BoseX` now raises a `TypeError` (instead of a `ValueError` for an
inappropriate operator type (was suggested in the original PR but was
never implemented).
- Minor documentation clean-up due to top-level access adjustment.
Remake of #6791
Context:
Had subprocess.Popen in the original code and should be removed for
security purposes

Description of the Change:
Changed to use Python standard lib

Benefits:
Security
Update logic in `LegacyDevice` to check for whether the device supports
`LinearCombination` or not.
