Patch for:

• Scheduler — Add hiddenDays option to hide arbitrary days of the week #33188

Known issues / observations:

• Kept export from common with @public (plus, reserved in aliases) & depreacted types' re-exports from ui - for backward compatibility in wrappers' common / index re-exports & component / ui modules bags / re-export (even our demos use them)

Pull request overview

This PR standardizes weekday typing across DevExtreme by introducing DevExpress.common.DayOfWeek (0–6) and migrating Scheduler/Calendar/Gantt firstDayOfWeek and Scheduler hiddenWeekDays typings to use it, while keeping FirstDayOfWeek as a deprecated alias. This aligns the public typings with the Scheduler “hide arbitrary days of the week” work in #33188.

Changes:

• Added DevExpress.common.DayOfWeek and deprecated DevExpress.common.FirstDayOfWeek in favor of it.
• Updated core TS declarations (dx.all.d.ts, common.d.ts, UI component .d.ts) and internal TS types to use DayOfWeek.
• Updated Angular/React/Vue wrapper typings to reference DayOfWeek (and adjusted hiddenWeekDays optionality).

• enumItemRenamings no longer contains the numeric-to-name mapping for weekday values. After renaming FirstDayOfWeek to DayOfWeek, the ASP.NET metadata generator will likely need the same mapping under the new enum/type name (e.g., 0 -> Sunday, ..., 6 -> Saturday) to keep generated enum member names stable and readable.

  '.*': {

• enumItemRenamings no longer contains a mapping for the day-of-week numeric union values. Since the corresponding public type was renamed to DayOfWeek, the ASP.NET metadata generator likely needs an equivalent DayOfWeek mapping (0..6 → Sunday..Saturday) to avoid generating invalid or less-friendly enum member names.

    'datetime': 'DateTime',
