📦 feat: Model & Assistants Combobox for Side Panel (#2380)

* WIP: dynamic settings

* WIP: update tests and validations

* refactor(SidePanel): use hook for Links

* WIP: dynamic settings, slider implemented

* feat(useDebouncedInput): dynamic typing with generic

* refactor(generate): add `custom` optionType to be non-conforming to conversation schema

* feat: DynamicDropdown

* refactor(DynamicSlider): custom optionType handling and useEffect for conversation updates elsewhere

* refactor(Panel): add more test cases

* chore(DynamicSlider): note

* refactor(useDebouncedInput): import defaultDebouncedDelay from ~/common`

* WIP: implement remaining ComponentTypes

* chore: add com_sidepanel_parameters

* refactor: add langCode handling for dynamic settings

* chore(useOriginNavigate): change path to '/c/'

* refactor: explicit textarea focus on new convo, share textarea idea via ~/common

* refactor: useParameterEffects: reset if convo or preset Ids change, share and maintain statefulness in side panel

* wip: combobox

* chore: minor styling for Select components

* wip: combobox select styling for side panel

* feat: complete combobox

* refactor: model select for side panel switcher

* refactor(Combobox): add portal

* chore: comment out dynamic parameters panel for future PR and delete prompt files

* refactor(Combobox): add icon field for options, change hover bg-color, add displayValue

* fix(useNewConvo): proper textarea focus with setTimeout

* refactor(AssistantSwitcher): use Combobox

* refactor(ModelSwitcher): add textarea focus on model switch
