Add an LDAP Info page: dynamic connection details + a ready-to-run ldap-client setup script

New admin-only page (nav: "LDAP Info") that answers "what do I put in my
app's LDAP settings" without reading a doc: LDAPS URL, base DN, user/group
search bases, user filter, username attribute, and an example bind DN, all
derived from the running conf.ldap + request host rather than hardcoded --
so it's always correct for the actual deployment, copy-button on every
field.

Also generates a copy-pasteable bash snippet that clones
theta42/ldap-client and writes its ldap.vars file with the real host/base
DN/sso_url already filled in (bind password and SSO API token left as
placeholders with inline instructions, since those need to be created,
not derived).
