• Update startDate/endDate element access in reservations.js to use getElementById and .value for filter query
• Change startDate/endDate input type to text to use flatpickr
• Remove hidden formatted inputs and update DatePickerSetupControl calls to pass DefaultDate

Pull request overview

Updates the Admin “Manage Reservations” date filters to use the Flatpickr-backed DatePickerSetupControl instead of native <input type="date">, and adjusts the client-side filtering code to read the new inputs correctly.

Changes:

• Switch startDate/endDate inputs from type="date" (and hidden formatted fields) to type="text" driven by DatePickerSetupControl with DefaultDate.
• Update reservations.js to read start/end dates from the new input elements via getElementById(...).value.
• Move search-clear.js into the main JS include block (removing the duplicate include at the bottom).
