Pin to unlock communicator

[magush27]

New PIN lock feature to enhance the security of the app's settings and board unlocking functionality. Users can now enable a 4-digit PIN lock in the navigation settings, which will require entering the correct PIN to unlock protected areas. The implementation covers both the settings UI and the board container logic, including a new PIN entry dialog component.

Changes:

PIN Lock Feature Implementation:

• Added pinLockEnabled and pinCode options to the navigation settings state, allowing users to enable/disable the PIN lock and set a 4-digit PIN.
• Updated the navigation settings UI to include switches and input fields for enabling PIN lock and entering the PIN, with validation and visibility toggle.

PIN Dialog Component:

• Added a new reusable PinDialog component for PIN entry, with support for input validation, visibility toggle, and error messaging.

Board Unlock Logic:

• Integrated PIN lock checks into the board lock/unlock flow in Board.container.js, displaying the PIN dialog when required and handling PIN validation and error states.

Internationalization:

• Added new internationalized messages for the PIN lock feature and dialog, ensuring all user-facing text is translatable.
