docs(bal): rewrite CHECK ALIVE help text (DATA/RAW modes) + fix two typos (v0.3.8)

Rewrite the CHECK ALIVE help popup (ThresholdTimeWidget.help_text) to explain
both modes, keeping the <b>CHECK ALIVE</b> title bold:
- DATA mode: set the check-alive date; on wallet open, if the date has passed
  the plugin asks whether to postpone the inheritance.
- RAW mode: when less than this time is missing, ask to invalidate; failing to
  invalidate delivers the transactions to the heirs; kept the d/y suffix help.

Fix two typos within this help text: 'less then' -> 'less than',
'currrent' -> 'current'.

Bump version to 0.3.8 across the four version files. CHANGELOG entry #14.

+## 14. Check-alive help text: DATA/RAW explanation and two typo fixes
+
+**Request:** rewrite the text inside the CHECK ALIVE help popup to explain both
+the DATA mode and the RAW mode, while keeping the **CHECK ALIVE** title in bold.
+
+**What changed:**
+- `bal/gui/qt/widgets.py`
+  - Updated `ThresholdTimeWidget.help_text` with the new wording:
+    - kept `<b>CHECK ALIVE</b>` bold;
+    - added a **DATA mode** paragraph (set the check-alive date; on wallet open,
+      if the date has passed, the plugin asks whether to postpone the
+      inheritance, assuming the user is still alive and in control);
+    - added a **RAW mode** paragraph (when less than this time is missing, ask
+      to invalidate; failing to invalidate in time delivers the transactions to
+      the heirs);
+    - kept the existing "d / y suffix" explanation.
+  - Fixed two typos in this help text: "less then" -> "less **than**", and
+    "currrent" -> "**current**" (only within the CHECK ALIVE help text).
+
+**Verification:**
+- `py_compile` on the changed file: OK.
+- `ruff check`: no new errors (only the pre-existing star-import noise and the
+  pre-existing F841 at line 547).
+- Full test suite: `239 passed`.
+
+**Outcome:** DONE (delivered as a test ZIP v0.3.8 for the user to try before
+commit).
