Vishnu Narayanan 039a311327 fix: consolidate widget rack-attack throttles with per-endpoint kill switches + saner defaults (#14376)
## Description

Consolidates all widget API throttles under the single
`ENABLE_RACK_ATTACK_WIDGET_API` flag, each with its own independent kill
switch and configurable limit, with defaults tuned from real prod
traffic.

Fixes https://linear.app/chatwoot/issue/INF-83
Related to https://linear.app/chatwoot/issue/INF-77

Parent flag stays default-true; installs that disabled it keep today's
behavior (no widget throttling). Each endpoint adds
`ENABLE_RACK_ATTACK_WIDGET_<X>` + `RATE_LIMIT_WIDGET_<X>`.

- **conversations create**: keyed on (IP, website_token), 30/min (was
per-IP 6/12h)
- **messages create**: new throttle, (IP, website_token), 60/min (was
unthrottled)
- **contact update**: fixes a dormant bug. `resource :contact` gives the
singular URL `/api/v1/widget/contact`, but the throttle checked plural
`/api/v1/widget/contacts` so it never fired. Now active (60/1h per IP).
- **widget load**: 5 to 200/1h, tuned from prod (real per-IP loads top
out ~50/hr; the higher tail is crawlers/scrapers)
- **transcript**: 5/1h retained

Token precedence: the (IP, website_token) throttles read `website_token`
via ActionDispatch (query wins), matching the controller, so a
body-supplied token cannot fork the throttle bucket.

## Type of change

- [x] Bug fix (non-breaking change which fixes an issue)

## How Has This Been Tested?

`ruby -c` and rubocop clean. No spec added, matching this file's
existing no-spec convention for throttles.
