Two fixes from the T3+T4 code review:
C1 (Critical): renderSectionBlock previously rendered all fields
regardless of kind. For fields with kind url/date/month_year/totp/etc.
(from CLI-created items), the editor showed a blank value input; if
the user typed anything, the input handler cast the kind to the
wrong thing and silently overwrote the structured value with a
string — destroying data. Fix: filter editor to supported kinds
(text/password/concealed); key data-* attributes by field.id (not
by index) so handlers look up the correct field regardless of what
the render loop emitted. Unsupported-kind fields survive save
untouched. A small muted note "N fields of unsupported kind (edit
via CLI)" flags preserved entries. +2 tests.
I1 (Important): totp.ts's kind-toggle reRender read the module-
scope sectionsExpanded flag which was only updated on structural
mutations — so toggling the disclosure open without adding/removing
anything left the flag stale, and clicking Random/BIP39 collapsed
the disclosure. Fix: read data-expanded from the live DOM before
innerHTML swap.
