fix(clients): restore upstream status visuals

[rynfar]

Problem

Pylon's DOTMATRIX status layer replaced the upstream status vocabulary with a custom animated glyph system. It drifted from current T3 status behavior, kept retired theme/settings roles alive, and made several active states visually expensive or semantically ambiguous.

Fix

• remove DOTMATRIX components, settings, theme roles, generated mobile variables, and internal documentation
• restore upstream-style dots, icons, task glyphs, pulse/ping motion, and semantic status colors using 5e63aea2df03e8ccc5c8a56cee4c067ecbd3d703 as the visual reference
• preserve Pylon-specific liveness, delegation, workflow, provider-update, theme-import, and mobile behavior
• retain legacy v2 theme-file compatibility while discarding retired status-only overrides
• document the restored status language and Reduce Motion behavior

Verification

• 25 focused test files: 464 tests passed
• typechecks passed for @t3tools/shared, @t3tools/contracts, @t3tools/web, @t3tools/mobile, and @t3tools/desktop
• changed-file lint and formatting passed
• generated mobile theme artifacts match the generator
• real-client browser pass completed at 1280×800 and 390×844 with no console errors or horizontal overflow
• verified approval/input semantics, settings cleanup, loaded pulse/ping animations, and responsive sidebar presentation
