fix(14-03): remove dead onSubmit branch in SendQuoteModal (CRM-12)

- Remove unreachable if (tab === "new") branch in onSubmit - the new-tab button has its own onClick navigation and never triggers form submit
- Escape unescaped double quotes in JSX text (react/no-unescaped-entities)
- generate_new field left as-is per plan (optional cleanup, out of scope)
- Log pre-existing useForm<any>/onSubmit(data: any) no-explicit-any lint errors to deferred-items.md (out of scope: fixing requires resolving a zodResolver/Resolver generic incompatibility with assignQuoteSchema's optional/default fields)
