hx-target="#card-<key>" is an invalid CSS selector for any key containing
a colon (every real bookmark key is "<site>:<series_id>"), so htmx threw
before swapping and the favourite/delete/chapter-override controls were
dead in the browser. Switch to the attribute-selector form
[id='card-<key>'], which querySelectorAll accepts regardless of the id's
characters.
Also close a validation gap in uiChapter: strconv.ParseFloat accepts
"NaN"/"Infinity"/"-Inf" with err == nil, and every comparison against NaN
is false, so num < 0 let both through to last_chapter_num and permanently
broke HasNewChapter. Reject non-finite values explicitly.
