Moved md from Phase 2 extensions to allowed formats, added extraction
handler (reuses txt handler), and updated plan_limits defaults to
include md for all plans.

The uploader should know their content type — auto-detection adds
complexity and currently just defaults to troubleshooting anyway.

Steps built by _build_procedural_tree() were stored under the "content"
key but StepDetail.tsx reads "description". Renamed the key so step
text and commands display correctly during session execution.

- _build_procedural_tree now maps AI node types (step, action, warning) to
valid procedural types (procedure_step, section_header, procedure_end)
- Generates 'title' field from content text — fixes "Unnamed step" in editor
- Auto-appends procedure_end step if AI didn't generate one
- Adds procedural validation gate at commit endpoint (same as troubleshooting)

- Add _repair_tree() post-build pass that fixes structural issues caused by
placed-set race conditions: demotes decisions with <2 children to actions,
hoists orphaned children as siblings, converts dead-end actions to solutions
- Add validation gate at commit endpoint — rejects trees that fail validation
with a 422 and descriptive error messages instead of saving invalid trees
- Update test fixtures to create valid multi-node tree structures
- Frontend: initialize currentNodeId from tree's actual root ID instead of
hardcoded 'root', fixing "Invalid tree structure" for KB-generated trees

Decision nodes with fewer than 2 buildable child targets now get
demoted to action nodes instead of creating invalid tree structures.
Also adds id fields to option objects (required by tree editor).

- Fix _build_troubleshooting_tree() to handle deep nesting, warning nodes,
and DAG deduplication (placed set prevents duplicate IDs)
- Fix step_sync VARCHAR(255) overflow on publish by truncating title
- Add "Approve All" button to KB review screen
- Add delete button (hover-reveal) to flow canvas nodes
