fix(swaylock): rewrite for vanilla swaylock 1.8.6

The previous file used swaylock-EFFECTS options, which the packaged swaylock
ignores. Documents that swaylock reads $XDG_CONFIG_HOME/swaylock/config on
every invocation, including hypridle's before_sleep_cmd and the $mod+m
keybind.

+# swaylock configuration -- VANILLA swaylock (packaged v1.8.6).
+#
+# swaylock reads $XDG_CONFIG_HOME/swaylock/config automatically, so this file
+# applies to every invocation, including hypridle's before_sleep_cmd and the
+# $mod+m keybind.
+#
+# IMPORTANT: the previous version of this file used swaylock-EFFECTS options
+# (clock, timestr, datestr, fade-in, effect-blur, effect-scale and a bare
+# `indicator`). The packaged swaylock is vanilla, and each of those lines logs
+#   swaylock: unrecognized option '--effect-blur=20x2'
+# + a full usage dump, then ignores it (verified against v1.8.6). So the file
+# was never fatal -- but none of its styling ever applied either, which is why
+# the lock screen always looked like a bare `swaylock -c 000000`. Keep only
+# names that appear in `swaylock --help` (check: every key here matches one).
+#
+# Want the blurred background + clock lock screen? Use hyprlock (installed and
+# configured at ~/.config/hypr/hyprlock.conf) -- that is what hypridle's
+# lock_cmd / 300s listener already call. Or install swaylock-effects from the
+# AUR and re-add the effect-* keys.
