* Scripts: close every msg_info block with msg_ok
Past-tense msg_info calls that should have been msg_ok, notices that opened a block before a prompt, and blocks without a closing msg_ok. These already left a stale spinner; with core's block stack they would resume it after every later msg_ok.
* Generate passwords with random_password
openssl rand -base64 | tr -dc | head -c returned fewer characters than asked for, and the unfiltered | cut variants put / and + into passwords that end up in DSNs and sed expressions. Secrets an app decodes as base64 are unchanged. Requires community-scripts/core#61.
* Keep data directories through CLEAN_INSTALL instead of copying them
create_backup copied uploads, storage and similar directories twice per update and needed their size again in free space. CLEAN_INSTALL_KEEP moves them aside instead. Only directories the upstream release does not ship, in scripts that restored right after the fetch. Requires community-scripts/core#61.
* Drop the 300s uv timeout overrides
setup_uv exports UV_HTTP_TIMEOUT=600 now; the scripts' 300 only lowered it. Requires community-scripts/core#61.
PR #14818 replaced the setup wizard curl with CLI commands but omitted
the schema migration step, causing fresh installs to fail when creating
the admin user. Trigger schema init via HTTP after config-ini.
Fixes#15828
