Subject: [PATCH] fix: replace broken chosen-rails gem with official Chosen
 v1.8.7 assets

## Problem

The chosen-rails gem's support-rails-8 branch has broken CoffeeScript
compilation that causes Chosen dropdowns to appear empty despite having
populated <option> elements in the DOM.

The CoffeeScript comprehension syntax was compiling to broken JavaScript
with uninitialized loop variables (`for (undefined; i < len; i++)`),
causing loops to never execute. This affected both option parsing and
DOM rendering.

## Root Cause

CoffeeScript 1.12.2 (from 2016) combined with the support-rails-8
branch produces incorrect JavaScript compilation for comprehension loops.

## Solution

Removed the chosen-rails gem dependency and replaced it with official
pre-compiled Chosen v1.8.7 assets in vendor/:

- vendor/assets/javascripts/chosen.jquery.js
- vendor/assets/stylesheets/chosen.css
- vendor/assets/images/chosen-sprite.png
- vendor/assets/images/chosen-sprite@2x.png

Updated application.js to require chosen.jquery from vendor instead of
the gem.

## Benefits

1. Avoids CoffeeScript compilation issues entirely
2. Removes unnecessary gem dependency
3. Full control over Chosen version
4. Simpler asset pipeline (no gem-based asset resolution)

## Additional Fixes

- Fixed JavaScript syntax error in application.js (chosen() options)
- Fixed script loading order (jQuery before Bootstrap)
- Added blank prompt option to members dropdown

## Testing

Verified working:
- Member directory dropdown (240 members)
- Search/filter functionality
- Keyboard navigation
- Single deselect option

## Future Consideration

This uses the jQuery-dependent Chosen library. Long-term, consider
replacing with a modern JavaScript alternative without jQuery dependency.
