task_stats contains short info about a task. To get a list of task_stats
in the module, one needs to request /task_manager/list_module_tasks/{module}.
To make identification and navigation between tasks easier, extend
task_stats to contain shard, start_time, and end_time.

tablet_repair_task_impl is run as a part of tablet repair. Make it
a child of tablet repair virtual task.
tablet_repair_task_impl started by /storage_service/repair_async API
(vnode repair) does not have a parent, as it is the top-level task
in that case.
No backport needed; new functionality

test: add test to check tablet repair child
service: add child for tablet repair virtual task
Currently, when the tablet repair is started, info regarding
the operation is kept in the system.tablets. The new tablet states
are reflected in memory after load_topology_state is called.
Before that, the data in the table and the memory aren't consistent.
To check the supported operations, tablet_virtual_task uses in-memory
tablet_metadata. Hence, it may not see the operation, even though
its info is already kept in system.tablets table.
Run read barrier in tablet_virtual_task::contains to ensure it will
see the latest data. Add a test to check it.
Fixes: #21975.

Replace remaining uses of boost::adaptors::transformed with std::views::transform
to reduce Boost dependencies, following the migration pattern established in
bab12e3a. This change addresses recently merged code that reintroduced Boost
header dependencies through boost::adaptors::transformed usage.

Extend tablet_virtual_task::wait to support resize tasks.
To decide what is a state of a finished resize virtual task (done
or failed), the tablet count is checked. The task state is set to done,
if the tablet count before resize is different than after.
Extend tablet_virtual_task::contains to check resize operations.
Methods that do not support resize tasks return immediately if they
are handling split or merge task.
now that we are allowed to use C++23. we now have the luxury of using
`std::ranges::to`.
in this change, we:
- replace `boost::copy_range` to `std::ranges::to`
- remove unused `#include` of boost headers

Standardize on one range library to reduce dependency load.
Unfortunately, std::views::concat (the replacement for boost::join),
is C++26 only. We use two separate inserts to the result vector to
compensate, and rationalize it by saying that boost::join() is likely
slow due to the need for type-erasure.

Extend tablet_virtual_task::wait to support migration tasks.
To decide what is a state of a finished migration virtual task
(done or failed), the tablet replicas are checked. The task state
is set to done, if the replicas contain the destination of a tablet
migration.
Extend tablet_virtual_task::get_status_helper to cover migration
tasks. get_status_helper is used by get_status and wait methods.
Waiting for a task in the latter will be modified in the following
patch.
Extend tablet_virtual_task::contains to check migration operations.
Returned virtual_task_hint contains also tablet_id (only for migration
tasks) and task_type.
Return immediately from methods that do not support migration
for non-repair task types. The methods' support for migration
will be implemented in the following patches.
these unused includes are identified by clang-include-cleaner. after
auditing the source files, all of the reports have been confirmed.
