position tooltips: titles read 'the Earthman' (article) + occupied gatekeeper circles now produce tooltips; FT flow dismisses the gameboard Brief — TDD

Three follow-ups from manual review:

1. Title article: the tooltip .tt-description (position circles + My Buds) prepends 'the ' so it reads 'the Earthman', matching the established '@handle the <Title>' convention + the visible bud-row. Touches _table_positions.html, _my_buds_item.html, and the async add-bud row builder in _bud_add_panel.html (was building data-tt-description without the article, diverging from the server-rendered rows). active_title_display always returns a value so the article is always well-formed. Tests updated: epic + billboard IT (data-tt-description='the Earthman'), the two My Buds FTs.

2. Initial-gatekeeper tooltips: under the gatekeeper .gate-backdrop, .position-strip circles are pointer-events:none, so mouseenter only reached a .gate-slot that contained a pointer-events:auto descendant (an OK/NVM/drop button). An occupied circle WITHOUT such a button never fired its tooltip. Re-enable .gate-slot.filled/.reserved (occupied, hoverable, no click action of their own) at (0,4,1) > the (0,3,1) suppressor; empty circles stay suppressed. room_gate already handled via .room-gate-page; Role Select covered by the same .role-select-backdrop variant.

3. FT flow: the @taxman 'Debits & credits' ledger Brief renders over the gameboard top and intercepts id_create_game_btn. Added dismiss_brief_if_present() before the create-game click in the gatekeeper + select_role FTs (the trinket FTs already carry their own dismisses).

Verified: 11 position-tooltip FTs, gatekeeper drop, both My Buds FTs, select_role create-game FT all green; full IT/UT suite 1604 green. The gatekeeper-circle pointer-events couldn't be FT-asserted reliably (synthetic mouseenter bypasses pointer-events; real-hover is flaky) — verified via the compiled-CSS cascade + the drop FT confirming the OK button still clicks.
