fix(forms): propagate touched state on blur

[smartm0use]

Summary

• always propagate the touched callback when a form component handles blur
• replace the programmatic touched-state test with real input and blur DOM events
• restore validation feedback after a user leaves an invalid field

The internal FormControl is already marked as touched by its native value accessor before the component blur handler runs. Checking this.control.touched therefore prevents the outer NgControl callback from being invoked, leaving reactive form controls untouched and suppressing validation feedback.

Verification

• npm run test (164 specs)
• npm run lint (existing warnings only)
• npm run build:lib
• npm run build
• npm run schematics:test (21 specs)

Fixes #756
