feat(pcbnew): collab adds board text natively (PCB_TEXT) incl. justification

Browse source 
A board-level graphic text (Place→Text) lands in Drawings() and would otherwise hit the
same asyncify-fragile (kicad_pcb …) envelope-blob wall as via/zone on add. So PCB_TEXT
reconstructs NATIVELY: itemToJson emits size/thickness/angle plus horizontal & vertical
justification, mirror, and bold/italic (the text string was already emitted for any
EDA_TEXT); makeItem builds a fresh PCB_TEXT and restores all of them. flushDiff skips the
blob for PCB_TEXT_T. Footprint child text is unaffected — it syncs by move, and its add
is carried by the footprint blob.

Justification matters: it anchors the glyphs relative to the text POSITION, so without it
a left-justified text reconstructed centered on the peer and rendered visibly offset even
though GetPosition() matched (which is why the anchor-only headless check missed it).

Verified two-tab in the real app: a left/bottom-justified bold text added in tab A
reconstructs in tab B at the exact position with matching justification + string. Headless:
a board-text round-trip add test (sample text is left/bottom-justified) asserts the
position AND that hjust/vjust/text round-trip. 7 passed, 1 skipped, 0 aborts.
