fudian 579c1b6b26 Fix: CouchDB Erlang cookie breaks vm.args (use hex) (#16361) ...

* CouchDB: generate an Erlang-safe (hex) cookie

ERLANG_COOKIE was generated with `openssl rand -base64 32`, whose output
contains +, / and = (e.g. "+w2dDazB/CrIZMsZu8edX4hn55QeRXOCi+hom25Lmm8=").
CouchDB writes the cookie into /opt/couchdb/etc/vm.args as
`-setcookie '<cookie>'`, and those characters break Erlang's vm.args
parsing, so couchdb.service fails to start on a fresh install (#16360).

Use `openssl rand -hex 32` instead: a 64-char hex string is alphanumeric,
needs no quoting, and is always a valid Erlang cookie. (Same 256-bit
entropy as the base64 of 32 bytes.)

Closes #16360

* Update install/apache-couchdb-install.sh
