refactor(js): replace deprecated jQuery shorthand event methods with .on() and .trigger()

This commit updates usage of deprecated jQuery event shorthand methods (e.g., `.click()`, `.scroll()`, `.focus()`) with their modern, explicit alternatives: `.on('<event>', ...)` for binding handlers and `.trigger('<event>')` for dispatching events.

- `$(...).scroll(fn)` → `$(...).on('scroll', fn)`
- `$(...).click(fn)` → `$(...).on('click', fn)`
- `$(...).focus()` → `$(...).trigger('focus')`
- Reviewed and replaced similar shorthand usages across the codebase

These shorthand event methods were convenient but are now deprecated due to ambiguity between *event binding* and *event triggering*. For example:
- `$(...).focus()` may either trigger or bind a handler depending on context — a source of confusion and bugs.
- Explicit separation using `.on()` (for binding) and `.trigger()` (for dispatching) improves code clarity and predictability.

These changes align with modern jQuery best practices and are necessary for compatibility with newer versions of jQuery.
