Debug View & Dropdown Improvements

[joepavitt]

Description

Dropdown Improvements

• Closes Dropdown widget requires entry of both Value and Label #335 - Dropdown no longer requires both label and value to be defined. If no label is found, will fall back to value.
• Closes Add the ability to the dropdown to specify the list of options by msg.options #285 - Dropdown options can now be configured with msg.options
• Documentation updated both in-Editor and in the online Docs.

Debugging Tool

• Added a new "Debug View" for Dashboard 2.0
• This provides Props summaries, most recent message received, and any dynamic properties that have been sent to a widget, and consequently overridden any defaults.

State Management

• Moves the default server-side store into a data.js
• Adds a second store called state.js which will track any dynamic properties

Documentation Updates

• Update "State Management" to reflect changes to server-side stores
• Add "Debugging" section to detail new tooling

Dependency Updates

• Upgrade to Vuetify 3.4.0 in order to get the more streamlined version of v-data-table
