ChuckBuildsandClaude Sonnet 5 560513d435 fix(web): remove redundant htmx:afterSwap script re-execution (was double-executing every partial's inline script)
Re-verified this CodeRabbit finding, previously deferred as "needs isolated
testing" - traced it to a confirmed, active bug rather than a style
concern:

htmx 1.9.10's own config defaults to allowScriptTags: true (confirmed in
the vendored htmx.min.js, which itself contains the same clone-and-reinsert
<script> mechanism internally). This means htmx ALREADY re-executes every
<script> tag in swapped content by default, exactly like a browser
navigating to a new page. The custom htmx:afterSwap listener in
htmx-config.js did the identical clone-and-reinsert a SECOND time on top of
htmx's own handling - so every inline <script> block in every HTMX-loaded
partial (overview, display, durations, plugin config, etc. - most partials
have one) executed twice per load.

Confirmed safe to delete outright, not just narrow: grepped every hand-written
JS file for a manual `dispatchEvent(... 'htmx:afterSwap' ...)` that might
have relied on this handler for a non-htmx code path (e.g. the direct-fetch
fallbacks like loadOverviewDirect) - none exists, so nothing depended on
this listener specifically; htmx's native handling covers every real
htmx-driven swap on its own.

Left in place, unchanged: the console.error/console.warn global override
a few lines up in the same file, which suppresses known-noisy
HTMX-timing-race messages. That one is a legitimate anti-pattern too
(broad substring matching can mask unrelated errors) but redesigning it
needs care to preserve real diagnostics while still hiding the specific
harmless races it targets - a scoped follow-up, not a same-day deletion
like this confirmed-duplicate handler.

Validation: all 27 fast web tests pass; JS brace/paren balance sanity
checked (no local Node/browser available in this sandbox to execute the
file directly - verify manually in-browser before merge).
