giles cea009084f Fix sx-browser.js navigation bugs: CSS tracking meta tag and stale verb info ...

Two fixes for sx-browser.js (spec-compiled) vs sx.js (hand-written):

1. CSS meta tag mismatch: initCssTracking read meta[name="sx-css-hash"]
   but the page template uses meta[name="sx-css-classes"]. This left
   _cssHash empty, causing the server to send ALL CSS as "new" on every
   navigation, appending duplicate rules that broke Tailwind responsive
   ordering (e.g. menu bar layout).

2. Stale verb info after morph: execute-request used captured verbInfo
   from bind time. After morph updated element attributes (e.g. during
   OOB nav swap), click handlers still fired with old URLs. Now re-reads
   verb info from the element first, matching sx.js behavior.

Also includes: render-expression dispatch in eval.sx, NIL guard for
preload cache in bootstrap_js.py, and helpers.py switched to
sx-browser.js.
