my-sea gear NVM: gatekeeper + picker nav-back to table hex instead of ejecting to gameboard — TDD

User-spec'd 2026-05-26: the gear menu's NVM was always nav-backing to /gameboard/ from every my-sea state, which ejects the user one step further than they want when bailing on the gatekeeper or the spread/crucifix picker. Both should nav-back to the my-sea TABLE HEX (the landing) — one step back, not all the way out.

## templates/apps/gameboard/_partials/_my_sea_gear.html

Now takes an optional `nvm_url` context variable; falls back to `{% url 'gameboard' %}` when unset. The onclick handler reads `{{ nvm_url }}` so callers can override per-page.

## templates/apps/gameboard/my_sea.html

```
{% if show_picker %}{% url 'my_sea' as nvm_url %}{% endif %}
{% include "apps/gameboard/_partials/_my_sea_gear.html" %}
```

Picker phase → nvm_url = my_sea landing (table hex). Sign-gate + landing phases fall through to the default (gameboard) — landing's NVM = "back out of my-sea entirely", which is the existing behaviour.

## templates/apps/gameboard/my_sea_gate.html

```
{% url 'my_sea' as nvm_url %}
{% include "apps/gameboard/_partials/_my_sea_gear.html" %}
```

Gatekeeper unconditionally nav-backs to the my-sea landing.

## Tests

`apps/gameboard/tests/integrated/test_views.py`:
- `MySeaViewTest.test_gear_nvm_navs_to_gameboard_on_landing_phase` — landing NVM still goes to /gameboard/ (regression guard).
- `MySeaViewTest.test_gear_nvm_navs_to_my_sea_landing_on_picker_phase` — picker NVM goes to /gameboard/my-sea/ (seeds a non-empty hand to trigger show_picker per views.py:277's `hand_non_empty or (phase_param and show_paid_draw)` logic).
- `MySeaGateViewTest.test_gear_nvm_navs_to_my_sea_landing_not_gameboard` — gatekeeper NVM goes to /gameboard/my-sea/ (and explicitly NOT /gameboard/).

## Verification

All 1364 IT+UT green. No FTs assert the gear-menu NVM target URL (per pre-change grep) so no test fixes required there.
