shareable URLs and configuration saving

Query params recreate a generate, named presets live in localStorage. Related: State, Schedule form.

1. URL. nuqs writes year, batch, campus, selectedSubjects.
2. classConfigs. Named objects in localStorage.

Edits in editedSchedule are not encoded in the URL.

Example:

https://jiit-timetable.tashif.codes/?year=2&batch=B12&campus=62&selectedSubjects=CS311,CI573

  Form[ScheduleForm] --> nuqs
  nuqs --> URL
  URL --> Home[HomeContent mount]
  Home --> Conflict{cachedScheduleParams?}
  Conflict -->|none| AutoGen
  Conflict -->|same| Keep
  Conflict -->|different| Dialog

UrlParamsDialog: override (queue pendingAutoGeneration), prefill, or view existing. Subject codes are split on commas and mapped to names via the campus JSON.

Auto-generate waits until mappings[campus][year] exists so Pyodide is not called with empty tables.

  Save[handleSaveConfig] --> LS[(classConfigs)]
  LS --> Load[handleSelectConfig]
  Load --> Submit[handleFormSubmit]
  LS --> Share[share dialog copies URL]
  LS --> Del[handleDeleteConfig]

Stored object: { year, batch, campus, selectedSubjects }. Duplicate names are rejected. Compare page reads the same classConfigs key to fill either side.

ActionButtons.handleShare copies window.location.href. That is the nuqs URL of the current form, which may already match the generated params.
