fix(notifications): Send dialog cancel no longer pre-sends + no duplicate PDF

Two user-reported bugs on S00056 (and visible on any SO/invoice):

Bug 1: Cancelling the Send dialog still sends the email.
  action_quotation_send is a button handler that returns a
  compose-dialog action synchronously. Our override was calling
  _dispatch('quote_sent', ...) AFTER super(), which immediately
  sends the email via template.send_mail() before the user ever
  sees the dialog. Clicking Cancel at that point only dismisses
  the already-sent email's compose window.

  Fix: removed the _dispatch call entirely from action_quotation_send.
  The Send button IS the manual-send path; Odoo's compose dialog
  (pre-populated with our FP: Quotation Sent template thanks to
  _find_mail_template) handles the send-or-cancel choice correctly.

  If an auto-quote-sent notification is ever wanted, it should be
  wired from a cron that scans SOs that just transitioned
  draft -> sent, not from the button handler. Noted in a code
  comment.

Bug 2: Two copies of the same PDF attached to every email.
  The mail.template records now carry report_template_ids (set by
  the post_init hook from the previous refactor) which Odoo uses to
  auto-attach PDFs on send_mail(). But the fp.notification.template
  records ALSO had attach_quotation / attach_sale_order / attach_invoice
  flags set, which cause _collect_attachments() to render the same
  PDF a second time and pass it in email_values.

  Fix: turned those three flags off in the XML data file. Other
  flags (attach_coc, attach_bol, attach_receipt, attach_thickness_report,
  attach_packing_list, attach_pod) stay on — those are genuinely
  different documents, not dupes.

  Because the records are noupdate="1", updated the post_init_hook
  to also backfill the flag changes onto existing DB rows so
  production instances get cleaned up on -u, not just fresh installs.

Smoke:
  attach_quotation=False attach_sale_order=False attach_invoice=False on all three records
  1 report per template (no dupes)
  action_quotation_send no longer contains _dispatch("quote_sent", ...)
