Constrain variant value constructor to supported types (#1614)
* 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

Updated Codacy badge link to reflect new project status.

* Fix Codacy badge display

* Constrain variant value constructor to supported types

Previously, the implicit value constructor of etl::variant could
participate in overload resolution for unsupported types, potentially
causing ambiguous calls before the assertion was triggered.

The static_assert are replaced by enable_if constraints. Note the same
approach is applied to other constructors and methods for consistency.
