fix: make press-only widget actions reachable from mouse-button binds

[Arcadiyyyyyyyy]

Work done

Follow-up to #7952, which fixed the chain action and flipped its
registration from "p" to "pt" so it could be triggered from mouse-button
binds. Reviewer feedback on that PR asked for a separate PR to audit the
other cases where the same "p" → "pt" change is appropriate. This is that
audit.

Background. Widget actions are registered with actionHandler:AddAction(self, name, fn, data, types),
where types selects the dispatch sets the action lives in:

• "p" (key-press) → keyPressActions, reached by keyboard binds via actionHandler:KeyAction.
• "t" (text) → textActions, reached by mouse-button binds and the console via actionHandler:TextAction.

An action registered "p"-only is invisible to the text path, so binding it to
a mouse button silently does nothing. On the text path the handler is invoked
exactly like a press (isRepeat = false, release = nil), so making a one-shot
press action "pt" is safe and simply extends it to mouse binds and the console.

Change. Converted 30 one-shot press actions across 14 widgets from "p"
to "pt":

Widget	Actions
camera_flip	cameraflip
cmd_blueprint	blueprint_create, blueprint_next, blueprint_prev, blueprint_delete, buildfacing, buildspacing
cmd_commandq_manager	command_skip_current, command_cancel_last
cmd_comselect	selectcomm
cmd_onoff	onoff
cmd_factoryqmanager	factory_preset
gui_attackrange_gl4	cursor_range_toggle, attack_range_inc, attack_range_dec
gui_teamstats	teamstatus_close
minimap_rotation_manager	minimap_rotate
gui_gridmenu	gridmenu_category, gridmenu_next_page, gridmenu_cycle_builder
gui_pregame_build	stop, buildfacing, buildspacing, buildmenu_pregame_deselect
unit_auto_group	add_to_autogroup, remove_from_autogroup, remove_one_unit_from_group, load_autogroup_preset
unit_key_select	select
unit_stateprefs	stateprefs_clearunit

Deliberately left as "p" (hold-to-activate). Every action that registers a
"p" press paired with an "r" release — the modifier is set true on press and
false on release — is not converted. A mouse/text bind cannot fire the
release, so adding "t" would leave the modifier stuck on. These are:
buildsplit, commandinsert, factory_preset_show, reclaim_highlight,
unit_stats, selectloop/selectloop_deselect/selectloop_add,
selectbox/selectbox_<modifier>, stateprefs_record, stateprefs_clear.
(Note stateprefs_clearunit is converted — it is one-shot and has no paired
release, unlike its siblings.)

No handler logic changed; only the types string on the AddAction calls.

Addresses Issue(s)

• Review feedback on fix: chain action ignores underscores in command names and mouse-button binds #7952

Test steps

1. Widget load / no errors (all conversions)

• Start a skirmish and let all default widgets load.
• Confirm no Lua errors in infolog.txt. All converted widgets that are
  enabled by default (CameraFlip, TeamStats, Attack Range GL4, Commander
  Selector, Onoff, Minimap Rotation Manager, Grid menu, Auto Group, Blueprint,
  Command Queue Manager, Pregame Queue, State Prefs V2) loaded cleanly with no
  error following their load line. A bad types string would throw during
  widget:Initialize() — none did. (cmd_factoryqmanager and unit_key_select
  are disabled by default and were not loaded; their change is inert until
  enabled.)

2. Mouse-button bind now works (the fix)

• /bind mouse5 cameraflip in the console, then press mouse5 → camera
  flips 180°. On master the identical bind does nothing. This before/after
  difference confirms the fix.
• Spot-checked additional converted actions from separate widgets via mouse
  bind (e.g. /bind mouse4 attack_range_inc cycles the range display;
  /bind mouse5 minimap_rotate steps minimap rotation) — all now respond to the
  mouse button.

3. Keyboard binds still work (regression)

• The same actions bound to a keyboard key behave exactly as before the
  change — no double-dispatch, no change in keyboard behaviour.

4. Hold-to-activate actions untouched (regression)

• Verified an excluded action (buildsplit, kept "p") still activates on
  keyboard hold and releases cleanly — no stuck modifier. Confirmed none of the
  paired press/release actions were converted.
