Fix enabled-sources checkbox not persisting when all unchecked

Browser omits checkbox fields from POST when none are checked, so the
prautoblogger_enabled_sources option retained its previous value (with
Reddit). Added a hidden input to the checkboxes renderer so an empty
value is always submitted. Also replaced the hardcoded "Collecting
sources from Reddit…" pipeline status with a dynamic message reflecting
actually-enabled sources.

Bump 0.6.2 → 0.6.3.

+### Fixed
+- **Unchecking all sources still used Reddit.** Browser omits checkbox fields
+  from POST when none are checked, so the `prautoblogger_enabled_sources`
+  option never updated. Added a hidden input so an empty value is always
+  submitted — unchecking all sources now correctly saves `[]`.
+- **Pipeline status hardcoded "Reddit".** The "Collecting sources…" stage
+  message now reflects the actually-enabled sources instead of always
+  saying "Reddit".
