Why

Angular 22.2 adds the strictUnclaimedEventNames compiler option: a (someEvent) binding that matches no output of the element's directives and no known DOM event becomes compile error NG8030 — catching typo'd / renamed outputs that currently fail silently.

What changes for us

118 tsconfigs set strictTemplates (e.g. projects/spikersoft/tsconfig.json ~L20); add strictUnclaimedEventNames: true under angularCompilerOptions (centralise in a shared base if possible).
Fix whatever it finds (dead bindings are bugs: the handler never runs). Custom-element / web-component event bindings may need allow-listing.

Acceptance criteria

option on for the app + all libraries
every finding fixed or deliberately allow-listed with a comment
typecheck/build green

Blocked by the Angular 22.2 upgrade ticket. Size: S-M (depends on findings).

Links: Blocked by #1165.
