ui/phase-20: ship-group inspector actions

Eight ship-group operations land on the inspector behind a single
inline-form panel: split, send, load, unload, modernize, dismantle,
transfer, join fleet. Each action either appends a typed command to
the local order draft or surfaces a tooltip explaining the
disabled state. Partial-ship operations emit an implicit
breakShipGroup command before the targeted action so the engine
sees a clean (Break, Action) pair on the wire.

`pkg/calc.BlockUpgradeCost` migrates from
`game/internal/controller/ship_group_upgrade.go` so the calc
bridge can wrap a pure pkg/calc formula; the controller now
imports it. The bridge surfaces the function as
`core.blockUpgradeCost`, which the inspector calls once per ship
block to render the modernize cost preview.

`GameReport.otherRaces` is decoded from the report's player block
(non-extinct, ≠ self) and feeds the transfer-to-race picker. The
planet inspector's stationed-ship rows become clickable for own
groups so the actions panel is reachable from the standard click
flow (the renderer continues to hide on-planet groups).

+"Ship groups stationed here" subsection of the planet inspector.
+The map deliberately hides on-planet groups (rendering them as
+offset points crowds the canvas), so this list is the player's
+view of which fleets sit in this orbit. Race attribution is
+best-effort:
   - LocalGroup → the player's own race (`localRace` prop).
   - OtherGroup on an `other`-kind planet → the planet's owner.
   - OtherGroup elsewhere → "foreign" placeholder; the engine's
     typed contract does not carry per-group ownership outside
     battle rosters.
 
-Rows are intentionally non-interactive in Phase 19. Phase 21+ will
-deliver a full ship-groups table view; clicking a row will then
-deep-link into that table with a `(planet, race)` filter pre-applied.
+Phase 20 makes own-ship rows interactive: clicking a row pivots
+the inspector to the corresponding ship-group inspector through
+the shared `SelectionStore`. The actions panel mounts on top of
+the existing ship-group inspector, so the row is the on-planet
+entry point for Send / Load / Modernize / etc. Foreign rows stay
+non-interactive — there are no actions to drive against another
+race's fleet. Phase 21+ will reuse the same row shape inside the
+ship-groups table view with an additional `(planet, race)` filter.
