Dominik Roth 3955fa42c7 Drop TargetType.HOSTILE_*, track allies as their own Ally collection
Two related changes:

1. TargetType.HOSTILE_ARTILLERY/HOSTILE_TANK renamed to ARTILLERY/TANK,
   dropping the baked-in hostility assumption from the type name
   itself (a type describes the unit kind now, not an allegiance).
   Migration entries added for both, plus the already-existing
   COASTAL_BATTERY one, so old save files still load.

2. A friendly contact ('FriendlyTank#1:', detected by stripping a
   leading 'Friendly'/'Hostile' word off the type word before matching
   it, see ocr.py's _resolve_target_type()) is NOT a Target with a flag
   flipped, it's tracked as a new, entirely separate Ally
   (Board.allies), with its own id namespace: an ally Tank#1 and a
   hostile Target Tank#1 are two unrelated things that happen to share
   an id, not a collision (verified directly, see the rendered
   screenshot both coexisting). Ally intentionally has none of Target's
   firing-relevant fields (shell/powder_charges/assignment/alive),
   allies are never fired on. 'Hostile' and no prefix at all both mean
   a regular (non-ally) Target, not-ally is the default.

   Wired through: Board.add_ally/remove_ally, placed_entities_all()/
   ambiguous_entities_all() (new 'ally' category, cyan on the map,
   distinct from every other category's color), solver.resolve_board()
   (allies' own clues resolve too), find_by_name() (an ally can be a
   clue reference target), save/load round-trip, a new 'Allies' header
   popover mirroring Targets' (position/hide/geo-overlay/remove, no
   shell/charge/alive controls), and ParsedInfo.allies as a same-shaped
   but separate dict from ParsedInfo.targets, merged by a new
   _merge_allies() alongside _merge_targets() in _merge_all().

Verified: full test suite (added a dedicated OCR test for the Friendly/
Hostile/bare-prefix routing), a GTK smoke test round-tripping an ally
through save/load and the popover build, and a rendered screenshot
showing an ally Tank#1 and a hostile Target Tank#1 both on the map at
once with the same id, distinct colors, no collision.

"""Regression coverage for every intel-text format ocr.py understands.
Each format below was added incrementally in response to a real
screenshot/paste the user hit, and at least one of them (the '<ref>:
<value>' grammar colliding with the 'Type#id:' header shape) has already
regressed silently once because there was no test suite to catch it.
One test per format, named after what it covers, so a future change
that breaks an old format fails loudly and specifically instead of
being noticed (or not) days later.
