Add FL e-Filing Portal integration (assisted submission, Phase 1)

- fl.efiling.submission: generates the 11th Circuit court filename
  ({LastName}_{CaseNumber}_{DocumentType}_{YYYYMMDD}.pdf), validates PDF/A via
  pikepdf (XMP pdfaid + OutputIntents, graceful if pikepdf missing), and tracks
  status (draft → validated → pending_manual → submitted → accepted/rejected/failed)
- Assisted flow: "Open e-Filing Portal" deep-links to eportal.flcourts.org
  (?caseNumber=… when available; base overridable via ir.config_parameter
  fl_efiling.portal_url); confirmation # capture; accepted/rejected mark the
  linked fl.document filed and log to chatter
- Phase 2 API stub (action_submit_api) reads creds/endpoint from ir.config_parameter
  and refuses to call an unconfirmed endpoint — no guessed URLs, no silent failure
- fl.efiling.wizard: pick document/attachment/filing_type, preview the filename,
  create + auto-validate the submission
- Wiring: model + wizard registered, ACL (admin/paralegal), e-filing views, Cases
  menu item, fl.case.efiling_submission_ids + Filings tab + Prepare e-Filing button
