fix(icons): align table block icon and 12-unit icon stroke with the emcn family (#6708)

The table/table_v2 blocks and the table trigger used a local lucide-shaped
TableIcon (stroke 2.0, full-bleed 24 viewBox, 3x3 grid) while every other
table surface used emcn's Table. Consolidate onto the emcn icon and drop the
local copy.

Nested tool-call rows in Chat applied no color class, so a non-brand block
icon inherited body text instead of --text-icon.

redo/undo/zoom-in/zoom-out draw 0.85 stroke on a 12-unit viewBox, rendering
0.992px at a 14px box against the family's 0.904px. 0.775 restores parity.
