[BUG] Location /books conflicts with COPS links using front controller setup

[mikespub]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The nginx default.conf.sample uses Location /books for internal X-Accel-Redirect links.

This overlaps with standard COPS links for book details when using a front controller setup (i.e. no index.php/ in links).

The default nginx config doesn't support front controller setup by default either, so users with default configs won't notice this at the moment.

COPS 4.2+ supports mapping of X-Accel-Redirect filepaths in config/local.php, so both issues can be corrected by using a new internal /_redirect_ location and adapting the default config files.

A new PR will be prepared when COPS 4.2.0 is released and pending #70 has been merged to avoid conflict.

Expected Behavior

Enable front controller and define mapping in COPS config/local.php and adapt nginx default.conf.sample to support both front controller setup and new internal redirect location
