_getCharacterList() had two bugs that silently dropped every
user-created persona from the group participant picker:
1. The /api/presets/templates endpoint returns a JSON array directly,
but the code read `data.templates` (always undefined). The forEach
over `data.templates || []` iterated over an empty array every time,
so no user templates were ever added.
2. Even if the array had been read correctly, the `t.isCharacter` guard
would have filtered them all out — user templates are saved by
presets.js without that flag, which is only present on built-in
PROMPT_TEMPLATES entries.
Fix: accept both the direct-array and the {templates:[]} shapes, drop
the isCharacter guard (user_templates are personas by definition), and
use the correct field name (system_prompt, not prompt) so the character
prompt actually reaches the group chat.
Fixes#1656
Both _getModels() and getAllModels() store the sorted copy in a cache
variable but return the original unsorted array on first invocation.
Subsequent calls return the cache (sorted), causing inconsistent
model picker ordering on first render.
Hoist the HTML-escape lookup table in static/js/ui.js out of the
String.replace callback so it is allocated once instead of on every
matched character. esc() is the canonical escaper aliased across 27
modules and runs on essentially every render, so this removes a lot of
short-lived garbage on the hottest text path. Output is byte-identical
(verified across null/undefined/emoji/attribute edge cases).
Also build the <select> option lists in cookbook-hwfit.js and group.js
by accumulating a string and assigning innerHTML once, instead of
`innerHTML +=` inside a forEach (which makes the browser re-parse the
element's markup on every iteration). Final DOM is unchanged.
Pure micro-optimizations; no behavior change.
