slot/token tooltips: 'expires <relative>' (lowercase, .row-ts timescale) + per-slot token_cost on GateSlot + '+ <Token>' deposited-token list — TDD

Three pieces of housekeeping on the token tooltips:

1. Expiry format. relative_ts is now distance-based (abs gap from now), so it formats FUTURE expiries with the same timescale rules it already uses for past .row-ts timestamps (<24h time, <7d weekday, <1y 'dd Mon', else +year) — past behaviour unchanged (abs is a no-op for past). The FREE-token wallet tooltip (Token.tooltip_expiry) and the position-circle .tt-expiry both read 'expires <when>' (lowercase, no majuscule); the position tooltip is server-formatted via the filter (JS just copies the attr — no JS date logic).

2. Per-slot token count moved off the user's CARTE token onto the slot model. New GateSlot.token_cost (PositiveSmallIntegerField default 1) — the per-seat expenditure count. _gate_positions reads slot.token_cost instead of the CARTE Token.slots_claimed high-water mark, which wrongly showed '6' on every CARTE-covered seat. Every slot now reads 1 (a CARTE covers each seat at cost 1, like any token); the field only rises above 1 when the rising-game-cost feature lands.

3. Per-slot deposited-token list. Under the '<n> Token(s) deposited' header the tooltip now lists a '+ <Token name>' bulleted <ul> — one entry today (a slot ejects its token on any re-deposit, so combinations aren't yet possible). Derived from the slot's debited_token_type (e.g. 'carte' -> 'Carte Blanche', 'Free' -> 'Free Token'); a CARTE across all six seats shows '+ Carte Blanche' on each. token_types is a list, future-ready for token combinations + elevated per-slot cost.

Rising-game-cost is NOT built (recon-confirmed), so the per-slot count is always 1 and the 2-token-slot FT is intentionally skipped per user.

Tests: relative_ts future-date unit tests; FreeTokenTooltipTest rewritten for the relative format (real datetime, no MagicMock/strftime); wallet FT + the two CARTE token-count tests updated to per-slot semantics (1 + 'Carte Blanche'); FREE-slot IT asserts the token-list + 'expires '. Full suite 1606 green; 11 position-tooltip FTs + wallet tooltip FT green.
