498dff9013 refactor: use the term unmount instead of dismount (#1478) 
* refactor: use UNMOUNT instead of DISMOUNT in code

This change updates the term DISMOUNT in constants to UNMOUNT.
Other occurrences (e.g. variable names) are left alone for now.

* refactor(ui): use unmount instead of dismount

This change updates the GUI text and replaces dismount with unmount.

* docs: update term dismount -> unmount

* refactor(cmdline): add unmount

This change adds an argument 'unmount' for command line usage, while
trying to deprecate the old disnount argument.
The current dismount argument/flag will still work to not introduce
a breaking change.

* docs: mention that /dismount is deprecated

This change fixes the shorthand version of the argument /unmount
It also adds back the info for /dismount and that it is deprecated.

453ff2880e Windows Driver: Make max work items count configurable. Increase default to 1024. Queue write IRPs. 
- Made the maximum work items count configurable to allow flexibility based on system needs.
  - Increased the default value of max work items count to 1024 to better handle high-throughput scenarios.
  - Queue write IRPs in system worker thread to avoid potential deadlocks in write scenarios.
