* Add docs and tutorial for etl::intrusive_avl_tree (#1608)
* Add docs and tutorial for etl::intrusive_avl_tree
Documents the intrusive AVL tree added in PR #1425: a full API reference
page under Containers/Trees, and a tutorial demonstrating ordered access
to intrusively-linked objects with unpredictable lifetimes, including
move support and destructor-driven automatic removal from the tree.

* Add complexity shortcode and document its usage
Introduces a {{< complexity >}} Hugo shortcode (with light/dark styling
for constant/logarithmic/linear/linearithmic/polynomial/exponential
classes) for rendering Big-O complexity inline, applies it throughout
the intrusive_avl_tree API reference in place of raw "O(...)" text, and
documents the Description/Complexity structure and supported classes in
DOCUMENTATION.md.

* Fix issues found by @CodeRabbit
* Put complexity notes on their own lines in intrusive_avl_tree docs
Move the complexity shortcode from the inline "**Complexity:**" label
to its own line under a "**Complexity**" label. Notes that give several
alternatives (e.g. amortized vs. worst-case) now show each one on a
separate line. Update the guideline in DOCUMENTATION.md to match.
* Update complexity examples in DOCUMENTATION.md
Add the hard line break after the "**Complexity**" label in the
example, and rewrite the list of supported complexity classes in the
new two-line format, including an example with several alternatives.
* Add logarithmic complexity example to DOCUMENTATION.md

* Fix circular reference in callback_timer_*
Fixes#967
* Unify timer tick() ordering and detect duplicate inserts
Address review feedback on #1611.
Replace the is_active() guard with a consistent tick() ordering across
all timer controllers: a repeating timer is now reinserted before its
callback is invoked or its message is sent, matching etl::callback_timer.
A callback that restarts the timer then replaces the existing entry
instead of causing a second insert. Applied to message_timer_atomic,
message_timer_interrupt and message_timer_locked as well, which are
affected in the same way.
Reject an insert of a timer that is already in the active list, rather
than linking it to itself, and record that it happened. The regression
tests now assert duplicate_insert_detected() instead of relying on the
resulting circular reference hanging the test.
