Support "control after generate" in vue

[AustinMroz]

Continuation of #6034 with

• Updated synchronization for seed
• Migrates NumberWidgetNumberInput to Reka UI so the control after generate button doesn't overlap with text
• Sychronizes control after generate state with litegraph and allows for serialization

Several issues from original PR have not (yet) been addressed, but are likely better moved to future PR

• fix step value being 10 (legacy system)
• ensure it works with COMBO
• ensure it works with FLOAT
• either implement or remove the config button functionality - think it should open settings?
