Refactor permission variable names (#3457)

## Refactor: Improve clarity of permission variable names

Renamed confusing `can[Action]` boolean variables to `prevent[Action]`
(e.g., `canPrint` -> `preventPrinting`) in `PasswordController.java`,
`AddPasswordRequest.java`, and `add-password.html`.


The previous `can[Action]` convention was misleading, as `true` meant
the action was *disallowed*. The new `prevent[Action]` naming directly
reflects the intent (`true` = prevented), improving code clarity.

**Changes:**

*   Updated variable names in controller logic
*   Updated `@Schema` descriptions in `AddPasswordRequest.java`
* Updated corresponding HTML element attributes (`id`, `name`, `for`) in
`add-password.html`

**Important Notes:**

* The underlying logic still inverts the boolean when setting
permissions (e.g., `AccessPermission.setCanPrint(!preventPrinting)`).
* User-facing UI text remains unchanged per request of @Frooodle in
#3420.

**Why not invert the API logic**
*   Inverting API (to can[action] logic) would either invalidate the UI
* Inverting API AND changing UI would warrant bigger translation effort
to change it in all languages
* This version is consistent (meaning what the UI says is actually done)
and preserve the UI language (meaning no translations needed) however it
is inconsistent with PDFBox methods naming scheme

**PDFBox**

* **PDFBox Interaction:** This refactor addresses the naming *within*
Stirling-PDF's API and Front-end layers only. The controller logic
intentionally inverts the `prevent[Action]` boolean
(`ap.setCanPrint(!preventPrinting)`) to correctly interact with the
underlying PDFBox methods. No further renaming related to these
permissions is necessary as the PDFBox methods themselves retain the
`can[Action]` names.


Underlying logic is not changed so it should work but just in case I
tested locally on an Adobe PDF that contained form in Chrome.
