Final round of visual polish — four decisions implemented

Final round of visual polish — four decisions implemented: (1) In the projects board, every column header now carries the flowing serif font (previously the page title did — it now matches all other titles).

Final round of visual polish — four decisions implemented: (1) In the projects board, every column header now carries the flowing serif font (previously the page title did — it now matches all other titles). (2) The quick-capture field looks the same everywhere: in the Inbox too, with the four token symbols (#, @, 📅, 👁) and live pills while you type — and the list fields now show the live pills as well. (3) Project cards show a compact date pill when a task carries a 📅 date — in the column board and in the Area. (4) Daily Space and Space Review now use the green Space System checkbox instead of the blue system checkmarks. Plus: uniform chip sizes in both rituals and real ✕ icons everywhere instead of text characters.
